[0002] With the rapid development of new energy technologies, portable energy storage devices are increasingly used in outdoor activities and emergency power supply scenarios. However, in severe weather conditions such as rain, traditional energy storage devices lack effective waterproofing measures, making them prone to water ingress at the device interfaces, seriously affecting safety and lifespan. Existing waterproofing solutions have the following drawbacks: When existing waterproof protective covers are installed on the energy storage unit, their structural design is unreasonable. When it is necessary to plug or unplug power connectors on the energy storage unit, the entire waterproof protective cover must be completely removed from the energy storage unit. This operation is not only cumbersome, but more importantly, it exposes the energy storage unit directly to rainwater, increasing the risk of equipment damage from rain. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a waterproof protective cover for enclosing the energy storage body. The technical solution is as follows: It includes a fixed cover and a rotating cover. The fixed cover has a fixing part that can be installed on the energy storage body. The rotating cover is rotatably installed on the fixed cover and can rotate relative to the fixed cover so that the rotating cover can switch between a shielded state and an open state.

[0006] Furthermore, this application also proposes that the fixed cover is provided with a rotating pin, the rotating cover is provided with a rotating hole, the rotating pin is inserted into the rotating hole, and the rotating cover can rotate relative to the fixed cover around the rotating pin.

[0007] Furthermore, this application also proposes that a limiting part is provided at the end of the rotating pin away from the fixed cover, so that when the rotating pin is inserted into the rotating hole, the rotating cover is limited between the fixed cover and the limiting part.

[0018] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In existing technologies, portable energy storage devices face the problem of rainwater intrusion into their interfaces when used outdoors. Traditional waterproof protective covers use a one-piece structure, requiring the complete removal of the cover to plug or unplug the power connectors, thus exposing the device to rain. This design poses a risk of protective failure under frequent operation scenarios, failing to balance ease of operation with waterproof reliability.

[0022] To address the aforementioned issues, designers discovered that the shortcomings of existing technologies stemmed from the conflict between the protective structure and operational requirements. Analysis revealed that dividing the protective cover into fixed and movable sections allowed for necessary operations while maintaining partial protection. Based on this approach, a combined structure of a fixed and a rotating cover was proposed, with the fixed section maintaining the main protection of the equipment and the movable section enabling partial opening and closing.

[0023] Therefore, please refer to Figure 1 This application proposes a combined structure of a fixed cover 110 and a rotating cover 120. The fixed cover 110 is provided with a fixing part 111 for mounting to the energy storage body 200, and the rotating cover 120 is mounted on the fixed cover 110 by a rotatable connection, and the switching between the shielded state and the open state is realized by rotation.

[0024] The fixed cover 110 is a protective component that is fixedly connected to the energy storage body 200. It can be a shell structure made of metal or engineering plastic, and its fixing part 111 can be connected to the energy storage body 200 via slide rails, clips, or bolts. The rotating cover 120 is a protective component with a rotating function. It can be rotatably connected to the fixed cover 110 using a hinge or shaft structure, and the rotation angle can be controlled between 0 and 180 degrees. The shielded state refers to the state where the rotating cover 120 completely covers the operating area of ​​the energy storage body 200, and the open state refers to the state where the rotating cover 120 rotates to expose the operating area.

[0025] Specifically, the fixed cover 110 is mounted on the surface of the energy storage body 200 via the fixing part 111, forming a basic protective structure. When it is necessary to operate the interface of the energy storage body 200, the operator rotates the rotating cover 120 to make it rotate around the fixed cover 110. At this time, the rotating cover 120 is in the open state, exposing the operating area. After the operation is completed, the rotating cover 120 is rotated in the opposite direction to return it to the shielded state, restoring the overall protective function. This structure avoids the operation of completely disassembling the protective cover through a partial opening and closing design.

[0026] Compared to existing technologies, traditional solutions require the complete removal of the protective cover during operation, leaving the equipment fully exposed to rainwater. This solution utilizes a split structure to achieve partial opening and closing, maintaining continuous protection from the fixed cover 110 during operation, significantly reducing the risk of water ingress. The introduction of a rotating structure ensures both ease of operation and continuity of protection.

[0027] Through the above technical solution, this application achieves the function of maintaining continuous waterproof protection when operating equipment in rainy conditions. Operators can plug and unplug interfaces without completely removing the protective structure. The fixed cover 110 continuously covers the main body of the equipment, and the rotating cover 120 only opens and closes partially in the operating area, effectively preventing rainwater from entering the equipment and solving the technical defects of traditional solutions that interrupt protection.

[0028] Please see Figure 1 and Figure 4 This application further proposes that the fixed cover 110 is provided with a limiting member 112, and the rotating cover 120 is provided with a guide groove 121, a first limiting groove 122, and a second limiting groove 123. The first limiting groove 122 and the second limiting groove 123 are respectively located at both ends of the guide groove 121, and the limiting member 112 limits the sliding within the guide groove 121; please refer to Figure 2 When the limiting member 112 is positioned within the first limiting groove 122, the rotating cover 120 is in the open state; please refer to Figure 3 When the limiting member 112 is limited to the second limiting groove 123, the rotating cover 120 is in a shielded state.

[0029] The limiting member 112 is a component fixed to the fixed cover 110 and used to limit the rotation range of the rotating cover 120. It can be implemented using a protrusion or pin structure, and its function is to achieve stable positioning of the rotating cover 120 through cooperation with the guide groove 121. The guide groove 121 is a channel formed on the rotating cover 120 that allows the limiting member 112 to slide. It can be implemented using an arc-shaped or straight groove structure, and its function is to provide a sliding path for the limiting member 112 to guide the rotation direction of the rotating cover 120. The first limiting groove 122 and the second limiting groove 123 are groove structures located at both ends of the guide groove 121, respectively. They can be implemented using a recess or a snap-fit ​​design, and their function is to lock the position of the rotating cover 120 in the open or closed state by engaging the limiting member 112.

[0030] Specifically, when the rotating cover 120 needs to be switched to the open state, an external force is applied to make the rotating cover 120 rotate around the fixed cover 110. At this time, the limiting member 112 slides along the guide groove 121 until it enters the first limiting groove 122. At this time, the position of the rotating cover 120 is locked, and the interface of the energy storage body 200 is fully exposed for operation. When the rotating cover 120 needs to be closed, it is rotated in the opposite direction to make the limiting member 112 slide along the guide groove 121 to the second limiting groove 123. At this time, the rotating cover 120 completely covers the interface of the energy storage body 200. During this process, the sliding cooperation between the limiting member 112 and the guide groove 121 prevents the rotating cover 120 from shifting during rotation, while the locking function of the first limiting groove 122 and the second limiting groove 123 ensures that the rotating cover 120 remains stable in the target position.

[0031] Compared to existing technologies, current solutions require the complete removal of the protective cover to operate the interface, exposing the equipment to rain. This solution, through the synergistic action of the limiting component 112 and the guide groove 121, allows the rotating cover 120 to switch states simply by rotating, without requiring complete disassembly, thus preserving waterproof functionality while improving operational convenience.

[0032] Through the above technical solution, this application realizes the rapid switching between the open and closed states of the rotating cover 120, avoiding the risk of equipment getting wet from repeated disassembly of the protective cover. At the same time, through the mechanical locking of the limiting groove and the limiting member 112, it ensures that the rotating cover 120 can remain stable in both states, preventing accidental displacement caused by external force collision or vibration.

[0033] Please see Figure 1 and Figure 7 This application further proposes that the fixed cover 110 is provided with a rotating pin 113, and the rotating cover 120 is provided with a rotating hole 124. The rotating pin 113 is inserted into the rotating hole 124, and the rotating cover 120 can rotate relative to the fixed cover 110 around the rotating pin 113.

[0034] The rotating pin 113 is a cylindrical connecting component fixed to the fixed cover 110, which can be made of metal or high-strength plastic, and is used to provide a rotation fulcrum for the rotating cover 120. The rotating hole 124 is a circular through hole opened in the rotating cover 120, which can be designed with a size matching the diameter of the rotating pin 113, so that the rotating pin 113 forms a clearance fit after insertion. The limiting part 114 is a flange structure provided at the end of the rotating pin 113, which can be formed by stamping or injection molding, and is used to prevent the rotating cover 120 from axially disengaging from the rotating pin 113.

[0035] Specifically, the fixed cover 110 and the rotating cover 120 are rotatably connected by the engagement of the rotating pin 113 and the rotating hole 124. When the power interface of the energy storage body 200 needs to be operated, the rotating cover 120 can be rotated around the rotating pin 113 to the open state, while the fixed cover 110 remains in the installed state to maintain its waterproof protection function. The limiting part 114, by covering the edge of the rotating hole 124, constrains the rotating cover 120 between the rotating pin 113 and the fixed cover 110, preventing the rotating cover 120 from axially shifting during rotation. This structure achieves the rotation function while ensuring that the rotating cover 120 and the fixed cover 110 are always in a stable connection state.

[0036] Compared with existing technologies, traditional waterproof protective covers 100 use a snap-on or sliding rail connection structure, which requires complete removal of the protective cover during disassembly, resulting in the energy storage body 200 being exposed to rainwater. In contrast, this solution uses the rotational engagement of the rotating pin 113 and the rotating hole 124 to allow the rotating cover 120 to be rotated only partially to complete the operation, while the fixed cover 110 continuously covers the key parts of the energy storage body 200, preventing rainwater intrusion.

[0037] Through the above technical solution, this application realizes the partial opening and closing function of the waterproof protective cover 100 during power interface operation, allowing the device to be used without complete disassembly, thus maintaining the continuity of waterproof protection and simplifying the operation steps. The mechanical cooperation structure between the rotating pin 113 and the rotating hole 124 has high reliability and can maintain a stable connection even in frequent opening and closing scenarios, effectively extending the service life of the device.

[0038] Please see Figure 7 This application further proposes that the end of the rotating pin 113 away from the fixed cover 110 is provided with a limiting part 114, so that when the rotating pin 113 is inserted into the rotating hole 124, the rotating cover 120 is limited between the fixed cover 110 and the limiting part 114.

[0039] Among them, the rotating pin 113 refers to the columnar structural component that connects the fixed cover 110 and the rotating cover 120. It can be made of metal or high-strength plastic, and its function is to provide a rotation axis for the rotating cover 120.

[0040] The limiting part 114 refers to the protruding structure provided at the end of the rotating pin 113. Specifically, it can be implemented by using an annular boss or a snap-fit ​​structure to restrict the rotating cover 120 from detaching from the fixed cover 110 along the axial direction.

[0041] Specifically, the rotating pin 113 passes through the mounting position of the fixed cover 110 and is inserted into the rotating hole 124 of the rotating cover 120, with a limiting part 114 formed at the end of the rotating pin 113. When the rotating cover 120 rotates around the rotating pin 113, the limiting part 114 and the fixed cover 110 together form an axial constraint, ensuring that the rotating cover 120 remains stably connected to the fixed cover 110 during rotation. This structure allows the rotating cover 120 to rotate freely within the space defined by the fixed cover 110 and the limiting part 114 without concern about component separation.

[0042] Compared to existing technologies, the rotating parts of traditional waterproof covers often lack axial restraint, leading to a risk of detachment. This solution, however, uses a restraint part 114 to create a physical barrier, maintaining the assembly relationship between the fixed cover 110 and the rotating cover 120 throughout the rotation process. The operation of disassembling the protective cover in existing technologies is simplified to directly rotating the rotating cover 120, avoiding the equipment exposure problems caused by complete disassembly.

[0043] Through the above technical solution, this application achieves a stable connection between the rotating cover 120 and the fixed cover 110, ensuring that the waterproof protective cover 100 maintains its structural integrity during frequent opening and closing operations. The rotating cover 120 can complete the state switching without completely detaching from the fixed cover 110, which not only avoids the energy storage body 200 from being exposed to rain during operation, but also improves the ease of operation of the equipment.

[0044] Please see Figure 1 This application further proposes that a lifting groove 125 is provided on the side of the rotating cover 120 away from the fixed cover 110, and the lifting groove 125 facilitates the driving of the rotating cover 120 to rotate relative to the fixed cover 110.

[0045] The lifting groove 125 refers to a recessed structure located on the edge of the rotating cover 120. Specifically, it can be implemented using a U-shaped or arc-shaped groove, with its depth and width adapted to accommodate the insertion of fingers or tools. This structure allows the operator to apply rotational force without directly contacting the surface of the rotating cover 120, avoiding operational difficulties caused by hand slippage.

[0046] The rotation of the rotating cover 120 relative to the fixed cover 110 refers to the external force transmitted through the lifting groove 125 to make the rotating cover 120 rotate around the rotation axis. Specifically, this can be achieved by applying force at a single point or from both sides. The lifting groove 125 is designed to be located on the side of the rotating cover 120 away from the fixed cover 110, which can form a lever effect and reduce the force required for rotation.

[0047] Specifically, when it is necessary to switch the state of the rotating cover 120, the operator inserts their finger or tool into the lifting groove 125 and applies force in a specific direction. At this time, the lifting groove 125 converts the external force into rotational torque, causing the rotating cover 120 to rotate around the rotating pin 113 of the fixed cover 110. During the rotation, the limiting member 112 slides along the guide groove 121 until it is engaged in the first limiting groove 122 or the second limiting groove 123, completing the switch between the open and closed states. The opening position of the lifting groove 125 forms a lever arm with the rotation axis, so that the operator only needs to apply a small force to achieve stable rotation of the rotating cover 120.

[0048] Compared to existing technologies, traditional solutions require complete disassembly of the protective cover to operate the energy storage body 200 interface. This solution, however, uses a lifting groove 125 to partially open and close the rotating cover 120, preventing the entire protective cover from detaching from the energy storage body 200. Existing technologies lack a dedicated force-applying structure, making rotation prone to jamming due to force point misalignment during operation. The directional guiding effect of the lifting groove 125 ensures the stability of the rotation trajectory.

[0049] Through the above technical solution, this application solves the problem that the traditional waterproof protective cover 100 requires complete disassembly during operation, resulting in equipment exposure, and achieves convenient interface operation while maintaining a waterproof state. The lever principle design of the lifting groove 125 reduces rotational resistance and avoids component wear caused by improper force application. At the same time, the directional force application characteristic can prevent positional displacement during rotation, ensuring the sealing reliability under the shielded state.

[0050] Please see Figure 4 This application further proposes that a clearance groove 115 is provided on the side of the fixed cover 110 away from the rotating cover 120, and the clearance groove 115 is used to avoid the handle of the energy storage body 200.

[0051] The clearance groove 115 refers to a recessed structure on the side of the fixed cover 110, which can be implemented using a U-shaped or rectangular opening. Its position corresponds to the handle mounting area of ​​the energy storage body 200, and is used to avoid interference with the handle during the installation of the fixed cover 110. The handle of the energy storage body 200 refers to a lifting component located on the outside of the energy storage device, usually used for handling or moving the device. It can be made of metal or plastic and is fixed to the surface of the energy storage body 200 by bolts or clips.

[0052] Specifically, during the installation of the mounting cover 110 onto the energy storage body 200, the clearance groove 115 accommodates the handle while maintaining a gap between it and the handle, so that the mounting cover 110 does not need to completely cover the area where the handle is located. When the mounting cover 110 is slidably installed via the guide rail and guide groove, the clearance groove 115 reserves space along the extension direction of the handle to ensure that the installation path between the mounting cover 110 and the energy storage body 200 is not blocked by the handle. When the protective cover is in the covered state, a sealing gap is formed between the opening edge of the clearance groove 115 and the side wall of the handle, preventing rainwater from seeping into the interior of the energy storage body 200 through this area.

[0053] Compared to existing technologies, the existing waterproof protective cover 100, lacking a clearance structure, must completely cover the surface of the energy storage body 200 during installation, resulting in the handle being obstructed and requiring the entire protective cover to be disassembled for operation. This solution, however, by creating a clearance groove 115 on the fixed cover 110, eliminates the need to cover the handle area, allowing direct operation of the handle even after the protective cover is installed, thus avoiding the risk of waterproofing failure caused by frequent disassembly.

[0054] Through the above technical solution, this application solves the problem of frequent disassembly caused by the obstruction of the handle in the traditional waterproof protective cover 100. While maintaining waterproof performance, it retains the operability of the handle, reduces the possibility of rainwater intrusion, and improves the safety and maintenance convenience of energy storage equipment in harsh environments.

[0055] Please see Figures 1 to 4 This application further proposes an energy storage device, including an energy storage body 200 and a waterproof protective cover 100, wherein a fixing part 111 can be installed on the energy storage body 200.

[0056] The fixing part 111 refers to the component that connects the waterproof protective cover 100 to the energy storage body 200. Specifically, it can be achieved by a structure that combines a guide rail and a locking block 116. The guide rail slides in conjunction with the guide groove on the energy storage body 200. After the locking block 116 engages with the locking hole 211, it restricts the sliding displacement, ensuring a stable installation between the fixing part 111 and the energy storage body 200.

[0057] Installation refers to the process of fixing the fixing part 111 to the energy storage body 200. Specifically, it can be achieved through sliding fit and snap-fit ​​structure. For example, after the guide slide rail slides along the guide slide groove to the target position, the snap block 116 is inserted into the snap hole 211 to complete the limit, thereby realizing quick disassembly or adjustment of the installation position.

[0058] Specifically, the waterproof protective cover 100 is mounted on the surface of the energy storage body 200 via the fixing part 111. The fixing part 111 and the mounting part 210 of the energy storage body 200 are fixed together by sliding and snap-fit. When it is necessary to operate the interface of the energy storage body 200, the rotating cover 120 can rotate around the fixing cover 110 to switch to the open state, without having to remove the entire waterproof protective cover 100 from the energy storage body 200, thus preventing the energy storage body 200 from being directly exposed to rainwater. When the rotating cover 120 is in the shielded state, it covers the interface area of ​​the energy storage body 200, preventing rainwater from entering.

[0059] Compared to existing technologies, the existing solutions require the complete removal of the protective cover when operating the interface, which results in the equipment getting wet in the rain. In contrast, this solution uses a rotatable protective cover structure to partially open the operating area while maintaining waterproof coverage. This avoids the cumbersome steps of complete disassembly and maintains continuous protection for non-operating areas.

[0060] Through the above technical solution, this application solves the problem that the traditional waterproof protective cover 100 requires complete disassembly, which leads to the equipment getting wet in the rain. Through the structure of fixed installation and partial opening and closing, only the necessary area is exposed during interface operation, while the rest is still protected by waterproofing, which significantly improves the convenience of use and the safety of the equipment.

[0061] Please see Figures 4 to 6 This application further proposes an energy storage device, including an energy storage body 200 and a waterproof protective cover 100. The energy storage body 200 is provided with a mounting part 210, and the fixing part 111 can be detached and installed by cooperating with the mounting part 210.

[0062] The mounting section 210 refers to the docking structure on the outer surface of the energy storage body 200 for supporting the fixing cover 110. Specifically, it can be implemented using two rows of parallel, spaced guide grooves, which extend along the length to form a linear constraint trajectory. The fixing section 111 refers to the connection structure at the bottom of the fixing cover 110 corresponding to the mounting section 210. Specifically, it can be implemented using two rows of parallel, spaced guide rails, which form a sliding pair with the guide grooves, achieving rapid positioning through the sliding trajectory. Detachable installation means that the fixing cover 110 and the energy storage body 200 form a non-fixed connection, specifically achieved through sliding assembly and snap-fit ​​limiting cooperation. When maintenance is required, it can be unlocked and separated along the rail direction.

[0063] Specifically, when the waterproof protective cover 100 needs to be installed, the guide rail at the bottom of the fixed cover 110 can be slid into the guide groove on the surface of the energy storage body 200 until the end of the rail reaches the preset engagement position at the end of the groove. At this time, the locking block 116 on the guide rail and the locking hole 211 in the guide groove are engaged, and the relative displacement between the rail and the groove is restricted by mechanical interference, thereby completing the installation and positioning of the fixed cover 110. When disassembly is required, only a reverse thrust needs to be applied to disengage the locking block 116 from the locking hole 211, and the guide rail can be pulled out along the groove direction. During this process, it is not necessary to completely remove the protective cover, and the rotating cover 120 can still maintain a shielded state to prevent rainwater from entering.

[0064] Compared to existing technologies, traditional solutions require detaching the entire protective cover from the energy storage body 200 when plugging or unplugging the power connector, resulting in the device interface being completely exposed to rainwater. This solution, however, utilizes a sliding assembly structure of slide rails and grooves, allowing the fixed cover 110 to be repositioned without completely detaching from the energy storage body 200, while the rotating cover 120 always covers the energy storage body 200, forming a continuous waterproof barrier.

[0065] Through the above technical solution, this application achieves rapid installation and removal of the waterproof protective cover 100 on the energy storage body 200, while ensuring that the rotating cover 120 continuously covers the device interface area during the plugging and unplugging of the power connector. This structure avoids the risk of the device getting wet from rain due to the complete removal of the protective cover in traditional solutions, and solves the contradiction between waterproof function and ease of operation in outdoor use scenarios.

[0066] Please see Figures 4 to 6 This application further proposes that the installation part 210 includes two rows of guide grooves, the two rows of guide grooves are arranged in parallel with a gap, and the fixing part 111 includes two rows of guide rails, the two rows of guide rails can be slidably installed on the two rows of guide grooves respectively.

[0067] Among them, the guide groove refers to the groove structure that extends along a specific direction. Specifically, it can be formed on the surface of the energy storage body 200 by injection molding process, and is used to guide the linear movement trajectory of the guide rail.

[0068] Among them, the guide rail refers to the protruding structure that matches the shape of the guide groove. Specifically, it can be made of metal stamping or plastic extrusion and is assembled and positioned with the guide groove through sliding contact.

[0069] Among them, the parallel setting of the interval means that the two rows of guide slides maintain a constant distance and the axes are parallel to each other. Specifically, it can be achieved by setting the positioning reference during mold processing to ensure that the guide slides are subjected to uniform force when sliding synchronously.

[0070] Among them, the locating hole 211 refers to the recessed structure provided along the extension direction of the guide groove, which can be formed by stamping or milling, and is used to form a mechanical interlock with the locating block 116.

[0071] Among them, the locking block 116 refers to the protruding structure set along the extension direction of the guide slide rail. Specifically, it can be made of elastic material by injection molding, and the locking and fixing with the locking hole 211 is achieved by deformation recovery force.

[0072] Specifically, during installation, the two rows of guide rails are aligned with the entrances of the two rows of guide grooves, and the waterproof protective cover 100 is pushed in a parallel direction, causing the guide rails to slide within the guide grooves until they reach the predetermined position. At this time, the locking block 116, due to elastic deformation, embeds itself into the corresponding locking hole 211, forming a mechanical limit and preventing the guide rails from shifting when not in operation. During disassembly, by applying a reverse thrust to disengage the locking block 116 from the locking hole 211, the waterproof protective cover 100 can be removed along the groove direction.

[0073] In some specific embodiments, the cross-sectional shape of the guide groove can be designed as a T-shaped groove, and the guide rail can be a corresponding T-shaped boss to enhance torsional resistance. The locking holes 211 can be set at equal intervals, for example, a group every 20 mm, and the spacing of the locking blocks 116 matches the spacing of the locking holes 211 to achieve multi-level adjustment.

[0074] Compared to existing technologies, traditional solutions use bolt fixing or integral snap-fit ​​structures, requiring complete separation of the waterproof protective cover 100 from the energy storage body 200 during disassembly, resulting in the equipment being exposed to rainwater. This solution, through a combination of sliding installation and snap-fit ​​limiting, allows for disassembly and assembly with only a linear push-pull motion. During operation, the waterproof protective cover 100 always covers the surface of the energy storage body 200, preventing water from entering the equipment interfaces.

[0075] Through the above technical solution, this application realizes the rapid installation and disassembly of the waterproof protective cover 100. When plugging and unplugging the power connector, only the rotating cover 120 needs to be partially moved, without completely removing the protective cover. This effectively maintains the continuous waterproof protection of the energy storage body 200 in severe weather, while reducing the risk of component wear caused by frequent disassembly and assembly.

[0076] Please see Figures 4 to 6 This application further proposes that the guide slide groove is provided with locking holes 211 at intervals along the extension direction, and the guide slide rail is provided with locking blocks 116 at intervals along the extension direction. The locking blocks 116 can be locked into the locking holes 211 to limit the position of the guide slide rail relative to the guide slide groove.

[0077] The guide groove refers to a groove structure on the energy storage body 200, which can be made of metal or plastic and is used to guide the sliding direction of the guide rail. The guide rail refers to a protrusion structure on the fixed cover 110, which can be designed with dimensions matching the guide groove, for example, its width is slightly smaller than the spacing between the inner walls of the guide groove, to achieve a sliding fit. The locking holes 211 refer to holes spaced apart along the length of the guide groove, which can be circular or square, for example, one hole is opened at a certain interval. The locking block 116 refers to a protrusion structure on the surface of the guide rail, which can be made of an elastic material, such as rubber or spring steel sheet, so that the locking block 116 can be inserted into the locking holes 211 during sliding.

[0078] Specifically, when the mounting cover 110 needs to be installed on the energy storage body 200, the guide rail slides along the guide groove, and the locking block 116 engages with different locking holes 211 in sequence during the sliding process. For example, when the locking block 116 is embedded in a certain locking hole 211, the position of the guide rail relative to the guide groove is fixed, thereby restricting the movement of the mounting cover 110. By selecting different locking holes 211 to cooperate with the locking block 116, the installation position of the mounting cover 110 can be adjusted, for example, the mounting cover 110 can be positioned at a specific height or angle of the energy storage body 200.

[0079] Compared with existing technologies, the installation of the mounting cover 110 and the energy storage body 200 in traditional solutions usually adopts bolt fastening or a single snap-fit ​​structure, which makes disassembly cumbersome and unable to flexibly adjust the position. This solution, through the interval cooperation of the locking block 116 and the locking hole 211, not only achieves quick installation and disassembly, but also allows the position of the mounting cover 110 to be adjusted according to actual needs, avoiding frequent disassembly that would expose the energy storage body 200 to rainwater.

[0080] Through the above technical solution, this application solves the problem that the position of the waterproof protective cover 100 of the traditional energy storage device is difficult to adjust after installation. The fixed cover 110 is quickly positioned and firmly fixed through the snap-fit ​​structure, ensuring that the protective cover can be adjusted without complete disassembly in rainy weather, effectively preventing rainwater from entering the interface area of ​​the energy storage body 200.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
