Description

Technical Field

[0001] This application belongs to the field of energy storage equipment technology, and more specifically, relates to an energy storage shell and an energy storage device. Background Technology

[0002] Energy storage devices mainly include energy storage shells and energy storage units installed inside the energy storage shells. When maintaining and adjusting the energy storage units and other components, it is necessary to open the energy storage shell. Currently, the shell cover and the shell body of the energy storage shell are generally connected by bolts, which makes it inconvenient to close and open the shell cover.

[0003] Based on the above situation, it is necessary to design a new energy storage shell to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to provide an energy storage housing and an energy storage device to solve the technical problem of inconvenient locking and unlocking operations of the housing cover in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] On one hand, an energy storage housing is provided, comprising a housing body, a housing cover, and a locking structure. The housing body has an internal cavity, and an opening and a plurality of limiting blocks spaced apart along the opening are provided at the upper end of the housing body. The housing cover is connected to the upper end of the housing body and can close the opening. The locking structure includes a first driving member, a transmission disk, and a plurality of locking pins. The first driving member passes through the housing cover and is rotatably connected to the housing cover. The transmission disk and the locking pins are located inside the housing cover. The transmission disk is fixedly connected to one end of the first driving member located inside the housing cover. The locking pins are slidably connected to the housing cover, and each locking pin corresponds to one of the limiting blocks. One end of each locking pin is slidably hinged to the transmission disk. The rotation of the transmission disk can drive all the locking pins to slide synchronously, so that the other end of each locking pin selectively abuts against the limiting block.

[0007] Specifically, by setting the transmission disc as the transmission structure between the first driving member and the plurality of locking pins, one first driving member can simultaneously drive multiple locking pins, thereby enabling a single unlocking or locking operation to simultaneously lock multiple different positions, effectively improving the locking / unlocking efficiency and reliability of the cover and the body.

[0008] As a technical solution, the shell cover includes an outer cover body and an inner connecting plate. The inner connecting plate is disposed inside the outer cover body, and the inner connecting plate is slidably connected to the outer cover body in a direction perpendicular to the outer cover body. The locking structure is disposed on the inner connecting plate.

[0009] Specifically, when the shell cover is in the closed state, the outer cover closes the opening, and the inner side of the outer cover abuts against the upper end of the shell body. The inner plate and the locking structure are located within the opening. By providing the slidable inner plate, the locking pin can move closer to or further away from the limiting block in a direction perpendicular to the outer cover, thereby ensuring that the outer cover can reliably fit against the shell body, preventing the outer cover from shaking and effectively improving the sealing reliability of the energy storage shell.

[0010] As a technical solution, the shell cover further includes a second driving member and a driving sleeve. The driving sleeve is fixedly disposed on the outer cover body. The second driving member passes through the driving sleeve and is threadedly connected to the driving sleeve. One end of the second driving member located inside the outer cover body is rotatably connected to the inner plate.

[0011] Specifically, by setting the second driving member and the driving sleeve to form a screw and nut structure through a threaded connection, the movement of the inner plate can be effectively controlled and the self-locking of the inner plate can be achieved, thereby improving the sealing reliability of the energy storage shell.

[0012] As a technical solution, the second driving member has a through hole, the first driving member passes through the through hole, and one end of the first driving member located on the outside of the outer cover extends out of the second driving member.

[0013] Specifically, by embedding the first driving member into the second driving member, the overall structure can be effectively improved in terms of compactness, which is conducive to the miniaturization of the structure and avoids excessive encroachment on the space of the accommodating cavity.

[0014] As a technical solution, the center of the transmission disk is connected to the first driving member, and the periphery of the transmission disk is provided with a plurality of waist-shaped holes; the locking column includes a column body and an auxiliary shaft that are fixedly connected, the column body is slidably connected to the inner plate, and the auxiliary shaft is inserted into the waist-shaped holes.

[0015] Specifically, by setting the mutually cooperating waist-shaped hole and the auxiliary shaft, the rotation of the transmission disk and the linear sliding of the locking pin are realized through a transmission connection, which is simple, reliable and low in cost.

[0016] As a technical solution, the locking pin has a locking groove at the end away from the transmission disc, and the bottom of the limiting block has a locking boss. The locking groove can abut against the locking boss to restrict the locking pin from retracting and sliding.

[0017] Specifically, by setting the mutually cooperating locking groove and locking protrusion, the locking pin cannot retract or slide in the closed state, effectively preventing accidental unlocking and thus effectively improving the locking reliability of the cover and the body. Further, to switch from the closed state to the open state, the operator needs to first rotate the second drive component, which moves the inner plate downwards, causing the locking groove to disengage from the locking protrusion. Then, the operator can rotate the first drive component, which drives the transmission disc to rotate, causing the locking pin to retract inwards. At this time, the locking pin and the limiting block are misaligned in the vertical direction, allowing the operator to lift the cover upwards and rotate it 90 degrees, placing the cover in the open state. Correspondingly, to switch from the open state to the closed state, the process is reversed.

[0018] As a technical solution, at least one of the limiting blocks is provided with a switch at its bottom, and the switch is triggered when the locking pin abuts against the limiting block.

[0019] Specifically, by setting the switch, the mechanical signal indicating whether the cover is in a closed state can be converted into an electrical signal, enabling rapid and effective identification of the closed state, thereby helping to improve the safety and reliability of the energy storage housing.

[0020] As a technical solution, the shell cover also includes two first mounting brackets, which are respectively disposed at both ends of the inner side of the outer cover body. The first mounting brackets are provided with a first hinge shaft and a second hinge shaft that are parallel to each other, and the center distance between the first hinge shaft and the second hinge shaft is a preset distance.

[0021] Two second mounting brackets are provided on one side wall of the shell body. The two second mounting brackets correspond one-to-one with the two first mounting brackets. The second mounting brackets are provided with mounting holes, which include a main sliding hole and a secondary sliding hole. The main sliding hole extends vertically, and the secondary sliding hole is an arc hole with the upper end of the main sliding hole as the center and the preset distance as the radius. The lower end of the secondary sliding hole communicates with the main sliding hole, and the upper end of the secondary sliding hole is at the same height as the upper end of the main sliding hole. The first hinge shaft and the second hinge shaft are inserted into the mounting holes.

[0022] Specifically, on the one hand, by setting the main sliding hole to extend vertically, the first hinge shaft and the second hinge shaft can slide up and down synchronously along the main sliding hole, thereby realizing the up and down movement of the outer cover. On the other hand, by setting the secondary sliding hole as an arc hole centered on the upper end of the main sliding hole and with the preset distance as the radius, when the first hinge shaft reaches the upper end of the main sliding hole, the second hinge shaft can continue to slide upward along the secondary sliding hole, thereby realizing the 90-degree rotation of the outer cover. This design allows the outer cover to achieve both up and down movement and rotation, which can avoid interference between the outer cover and the shell body during rotation and improve the sealing effect in the closed state.

[0023] As a technical solution, the energy storage housing also includes a handle, which is hinged to the housing body. The housing body is provided with at least two sets of insertion holes, and the handle is provided with a resilient pin that can be inserted into any set of insertion holes.

[0024] Specifically, by setting the mutually cooperating elastic pins and two or more sets of the plug holes, the handle can be positioned in two or more different positions, thereby improving the flexibility of the handle and its applicability to different application scenarios.

[0025] On the other hand, an energy storage device is provided, the energy storage device comprising an energy storage housing according to any of the above, and an energy storage unit installed within the energy storage housing.

[0026] The beneficial effects of the energy storage shell and energy storage device provided in this application are as follows:

[0027] By setting the transmission disc as the transmission structure between the first driving member and the plurality of locking pins, one first driving member can simultaneously drive multiple locking pins, thereby enabling a single unlocking or locking operation to simultaneously lock multiple different positions, effectively improving the locking / unlocking efficiency and reliability of the cover and the body.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0056] Embodiments of this application provide an energy storage housing, such as Figures 1 to 6 As shown, the energy storage housing includes a main body 1, a cover 2, and a locking structure 3. The main body 1 has an internal cavity 11, and the upper end of the main body 1 has an opening 12 and several limiting blocks 13 spaced apart along the opening 12. The cover 2 is connected to the upper end of the main body 1 and can close the opening 12. The locking structure 3 includes a first driving member 31, a transmission disk 32, and several locking pins 33. The first driving member 31 passes through the cover 2 and is rotatably connected to the cover 2. The transmission disk 32 and the locking pins 33 are located inside the cover 2. The transmission disk 32 is fixedly connected to one end of the first driving member 31 located inside the cover 2. The locking pins 33 are slidably connected to the cover 2, and the locking pins 33 are correspondingly arranged with the limiting blocks 13. One end of each locking pin 33 is slidably hinged to the transmission disk 32. The rotation of the transmission disk 32 can drive all the locking pins 33 to slide synchronously, so that the other end of the locking pin 33 selectively abuts against the limiting block 13.

[0057] Specifically, by setting the transmission disc 32 as the transmission structure between the first driving member 31 and several locking pins 33, one first driving member 31 can drive multiple locking pins 33 simultaneously, so that one unlocking or locking operation can simultaneously achieve locking at multiple different positions, effectively improving the locking / unlocking efficiency and reliability of the cover 2 and the body 1.

[0058] In one embodiment, such as Figure 1 and Figure 4 As shown, the cover 2 has a closed state and an open state. In the closed state, the cover 2 closes the opening 12, and the inner side of the cover 2 fits against the upper end of the shell body 1. In the open state, the opening 12 is exposed, and the cover 2 and the opening 12 form a 90-degree angle.

[0059] Specifically, when the cover 2 is closed, the side of the cover 2 closest to the receiving cavity 11 is the inner side, and the side of the cover 2 furthest from the receiving cavity 11 is the outer side.

[0060] In one embodiment, such as Figures 1 to 3 As shown, the first driving member 31 has a driving head 311 at one end located on the outer side of the housing cover 2. The driving head 311 is used by the operator to rotate the first driving member 31. The first driving member 31 is located at the center of the housing cover 2, and the rotation axis of the first driving member 31 is perpendicular to the housing cover 2. The transmission disc 32 is parallel to the housing cover 2, and the sliding direction of the locking pin 33 is parallel to the housing cover 2.

[0061] In one embodiment, such as Figures 1 to 6 As shown, the cover 2 is square, and there are four locking pins 33, which are respectively oriented towards the four sides of the cover 2. The body 1 is cuboid, and the number of limiting blocks 13 is equal to the number of locking pins 33. The four limiting blocks 13 are respectively set on the four side walls of the body 1 near the opening 12. In the closed state, the locking pins 33 are located below the limiting blocks 13, thereby restricting the cover 2 from moving away from the body 1, and realizing the locking connection between the cover 2 and the body 1.

[0062] In one embodiment, such as Figure 1 and Figure 3 As shown, the locking structure 3 also includes a connecting plate 34, through which the first driving member 31 and the transmission plate 32 are fixedly connected. One end of the first driving member 31 located on the outer side of the cover 2 is provided with a mounting groove 312 for accommodating an indicator light or display screen. The first driving member 31 also has a wiring hole 313, which penetrates the first driving member 31. One end of the wiring hole 313 communicates with the mounting groove 312, and the other end communicates with the receiving cavity 11. In a specific implementation, the first driving member 31 also includes a light-transmitting plate 314, which encloses the mounting groove 312.

[0063] In one embodiment, such as Figures 1 to 6 As shown, the cover 2 includes an outer cover body 21 and an inner connecting plate 22. The inner connecting plate 22 is disposed inside the outer cover body 21, and the inner connecting plate 22 and the outer cover body 21 are slidably connected in a direction perpendicular to the outer cover body 21. The locking structure 3 is disposed on the inner connecting plate 22.

[0064] Specifically, when the shell cover 2 is closed, the outer cover 21 closes the opening 12, and the inner side of the outer cover 21 abuts against the upper end of the shell body 1. The inner plate 22 and the locking structure 3 are located inside the opening 12. By providing a sliding inner plate 22, the locking pin 33 can move closer to or further away from the limiting block 13 in a direction perpendicular to the outer cover 21, thereby ensuring that the outer cover 21 can reliably fit against the shell body 1, preventing the outer cover 21 from shaking and effectively improving the sealing reliability of the energy storage shell.

[0065] In one embodiment, such as Figures 1 to 6 As shown, a guide post 23 is provided on the inner side of the outer cover 21, and a guide hole 223 is provided on the inner plate 22. The guide post 23 passes through the guide hole 223 and is slidably connected to the guide hole 223. Furthermore, there are four guide posts 23 and four guide holes 223, and each guide post 23 corresponds to a guide hole 223.

[0066] In one embodiment, such as Figure 1 and Figure 3 As shown, the cover 2 also includes a second driving member 24 and a driving sleeve 25. The driving sleeve 25 is fixedly installed on the outer cover body 21. The second driving member 24 passes through the driving sleeve 25 and is threadedly connected to the driving sleeve 25. One end of the second driving member 24 located inside the outer cover body 21 is rotatably connected to the inner plate 22.

[0067] Specifically, by setting the second driving component 24 and the driving sleeve 25 with a threaded connection to form a screw nut structure, the movement of the inner plate 22 can be effectively controlled and the self-locking of the inner plate 22 can be achieved, thereby improving the sealing reliability of the energy storage shell.

[0068] In one embodiment, such as Figure 3 As shown, the drive sleeve 25 has a T-shaped structure and includes a transmission part 251 and a fixing part 252. The transmission part 251 has a threaded hole that is connected to the second drive member 24. The fixing part 252 is located at one end of the transmission part 251 located outside the outer cover 21. The transmission part 251 is fixedly connected to the outer cover 21 through the fixing part 252.

[0069] In one embodiment, such as Figure 3 As shown, the second driving member 24 has a through hole, the first driving member 31 passes through the through hole, and one end of the first driving member 31 located outside the outer cover 21 extends out of the second driving member 24.

[0070] Specifically, by embedding the first driving member 31 into the second driving member 24, the overall structure can be effectively improved in terms of compactness, which is conducive to the miniaturization of the structure and avoids excessive encroachment on the space of the accommodating cavity 11.

[0071] In one embodiment, such as Figure 3 As shown, the second driving member 24 is positioned between the driving head 311 and the transmission disk 32, so that as the second driving member 24 drives the inner plate 22 to slide, the first driving member 31 and the transmission disk 32 move with the second driving member 24, thereby realizing that the inner plate 22 and the locking structure 3 move up and down synchronously.

[0072] In one embodiment, such as Figure 3As shown, one end of the first drive member 31 located inside the outer cover 21 extends out of the second drive member 24.

[0073] In one embodiment, such as Figure 3 As shown, the second driving component 24 includes a driving tube 241, and a control plate 242 and a rotating plate 243 disposed at both ends of the driving tube 241. The driving tube 241 is threadedly connected to the driving sleeve 25. The control plate 242 is located on the outside of the outer cover 21, and the rotating plate 243 is located on the inside of the outer cover 21. The cover 2 also includes a rotating cover 26. The rotating cover 26 is fixedly connected to the inner plate 22. The rotating plate 243 is limited between the inner plate 22 and the rotating cover 26, and the rotating plate 243 can rotate relative to the inner plate 22 and the rotating cover 26.

[0074] Specifically, by setting up the control panel 242, the operator can easily rotate the second drive component 24; by setting up the cooperating rotating disk 243 and rotating cover 26, the rotating disk 243 can rotate and drive the inner plate 22 to move up and down.

[0075] In one embodiment, such as Figure 3 As shown, the control panel 242 is perpendicular to the rotation axis of the drive tube 241, and the rotating disk 243 is parallel to the control panel 242.

[0076] In one embodiment, a planar bearing is provided on the rotating disk 243, located between the rotating disk 243 and the inner plate 22. By providing the planar bearing, the resistance during the rotation of the second drive member 24 can be reduced, thereby reducing the difficulty of operation for the operator and improving the ease of operation.

[0077] In one embodiment, the rotating cover 26 is disposed on the side of the inner plate 22 near the transmission disk 32, and a plane bearing is provided between the rotating cover 26 and the transmission disk 32.

[0078] In one embodiment, such as Figures 1 to 6 As shown, the center of the transmission disk 32 is connected to the first driving member 31, and the periphery of the transmission disk 32 is provided with a number of waist-shaped holes 321; the locking column 33 includes a column body 331 and an auxiliary shaft 332 that are fixedly connected, the column body 331 is slidably connected to the inner plate 22, and the auxiliary shaft 332 is inserted into the waist-shaped hole 321.

[0079] Specifically, by setting mutually cooperating oblong holes 321 and auxiliary shafts 332, the transmission connection between the rotation of the transmission disc 32 and the linear sliding of the locking pin 33 is realized. The structure is simple, reliable, and low in cost.

[0080] In one embodiment, such as Figures 1 to 6As shown, the bottom of the inner plate 22 is provided with a guide block 221, which corresponds one-to-one with the locking pin 33. The locking pin 33 passes through the guide block 221 and is slidably connected to the guide block 221.

[0081] In one embodiment, such as Figure 6 As shown, the transmission disc 32 includes a disc body 322 and several extensions 323 fixedly disposed around the disc body 322. A waist-shaped hole 321 is disposed on each extension 323. The inner plate 22 has at least one set of limiting posts 222 on the side near the transmission disc 32. Each set of limiting posts 222 includes two uprights, distributed on both sides of the extension 323, used to limit the swing angle of the extension 323, thereby limiting the sliding range of the locking post 33. This ensures that the locking post 33 can reliably cooperate with the limiting block 13 to effectively lock the cover 2 and prevents the locking post 33 from detaching from the guide block 221, thus guaranteeing the installation reliability of the locking post 33. In specific implementation, the number of sets of limiting posts 222 is equal to the number of locking posts 33, that is, each extension 323 is provided with a corresponding set of limiting posts 222.

[0082] In one embodiment, such as Figures 1 to 6 As shown, the locking pin 33 has a locking groove 333 at the end away from the transmission disc 32, and the bottom of the limiting block 13 has a locking boss 131. The locking groove 333 can abut against the locking boss 131 to limit the retraction and sliding of the locking pin 33.

[0083] Specifically, by setting mutually cooperating locking grooves 333 and locking protrusions 131, the locking pin 33 cannot retract or slide in the closed state, effectively preventing accidental unlocking and thus effectively improving the locking reliability between the cover 2 and the body 1. Furthermore, to switch from the closed state to the open state, the operator needs to first rotate the second drive component 24, which drives the inner plate 22 downwards (i.e., from...). Figure 7 and Figure 8 The state becomes Figure 9 and Figure 10 (in the state of engagement), causing the locking groove 333 to disengage from the locking boss 131. Then, the operator can rotate the first drive member 31, which in turn drives the transmission disc 32 to rotate, causing the locking pin 33 to retract inward (i.e., from the state of engagement). Figure 9 and Figure 10 The state becomes Figure 11 and Figure 12 In the open state, the locking pin 33 and the limiting block 13 are vertically misaligned, allowing the operator to lift the cover 2 and rotate it 90 degrees, thus opening the cover 2. Conversely, switching from the open to the closed state is the reverse process.

[0084] In one embodiment, such as Figure 2 As shown, the width of the snap-fit ​​groove 333 is greater than the width of the snap-fit ​​boss 131. This design can effectively reduce the fitting accuracy requirements between the snap-fit ​​groove 333 and the snap-fit ​​boss 131, thereby reducing production difficulty and cost. In specific implementation, the width of the snap-fit ​​groove 333 is equal to 1.5 to 2 times the width of the snap-fit ​​boss 131.

[0085] In one embodiment, at least one limit block 13 is provided with a switch at its bottom, which is triggered when the locking pin 33 abuts against the limit block 13.

[0086] Specifically, by setting a switch, the mechanical signal indicating whether the cover 2 is in the closed state can be converted into an electrical signal, enabling rapid and effective identification of the closed state, thereby helping to improve the safety and reliability of the energy storage shell.

[0087] In practice, the switch is signal-connected to the output module of the energy storage device. When the switch is triggered, the output module is allowed to output electrical energy; when the switch is not triggered, the output module is prohibited from outputting electrical energy. This design effectively improves the safety of the energy storage device during the process of outputting electrical energy.

[0088] In one embodiment, such as Figures 1 to 6 As shown, the shell cover 2 also includes two first mounting brackets 27, which are respectively disposed at both ends of the inner side of the outer cover body 21. The first mounting brackets 27 are provided with a first hinge shaft 28 and a second hinge shaft 29 that are parallel to each other. The center distance between the first hinge shaft 28 and the second hinge shaft 29 is a preset distance. One side wall of the shell body 1 is provided with two second mounting brackets 14, which correspond one-to-one with the two first mounting brackets 27. Each second mounting bracket 14 has a mounting hole 15, which includes a main sliding hole 151 and a secondary sliding hole 152. The main sliding hole 151 extends vertically, and the secondary sliding hole 152 is an arc-shaped hole with the upper end of the main sliding hole 151 as its center and the preset distance as its radius. The lower end of the secondary sliding hole 152 communicates with the main sliding hole 151, and the upper end of the secondary sliding hole 152 is at the same height as the upper end of the main sliding hole 151. The first hinge shaft 28 and the second hinge shaft 29 are inserted into the mounting hole 15.

[0089] Specifically, on the one hand, by setting the main sliding hole 151 to extend vertically, the first hinge shaft 28 and the second hinge shaft 29 can slide up and down synchronously along the main sliding hole 151, thereby realizing the up and down movement of the outer cover 21; on the other hand, by setting the secondary sliding hole 152 as an arc hole with the upper end of the main sliding hole 151 as the center and a preset distance as the radius, when the first hinge shaft 28 reaches the upper end of the main sliding hole 151, the second hinge shaft 29 can continue to slide upward along the secondary sliding hole 152, thereby realizing the 90-degree rotation of the outer cover 21. This design allows the outer cover 21 to realize both up and down movement and rotation, which can avoid interference between the outer cover 21 and the shell body 1 during rotation and improve the sealing effect in the closed state. In the process of opening the shell cover 2, the shell cover 2 is finally lifted upward and rotated 90 degrees, which specifically includes two state change processes, namely from Figure 11 and Figure 12 The state becomes Figure 13 and Figure 14 The state, and then from Figure 13 and Figure 14 The state eventually switched to Figure 4 The state has reached the open state.

[0090] In the specific implementation process, such as Figure 5 As shown, the length of the main sliding hole 151 is greater than the preset spacing, and the length of the main sliding hole 151 is less than twice the preset spacing. This design can ensure that the outer cover 21 can move up and down, and can also prevent the first hinge shaft 28 from entering the secondary sliding hole 152, ensuring that the movement trajectory of the first hinge shaft 28 is only up and down, thus making the movement process of the outer cover 21 unique and clear, effectively improving the movement reliability of the outer cover 21.

[0091] In one embodiment, such as Figure 2 and Figure 5 As shown, a magnetic suction component 16 is provided on the second mounting bracket 14. The magnetic suction component 16 is located at the upper end of the secondary sliding hole 152. When the outer cover 21 is in the open state, the magnetic suction component 16 can provide a suction force to the second hinge shaft 29, so that the outer cover 21 is relatively stably kept in the open state.

[0092] In other embodiments, the second mounting bracket 14 is provided with an elastic buckle located at the upper end of the secondary sliding hole 152. When the outer cover 21 is in the open state, the elastic buckle can engage the second hinge shaft 29, so that the outer cover 21 remains relatively stable in the open state.

[0093] In one embodiment, such as Figures 15 to 18As shown, the energy storage housing also includes a handle 4, which is hinged to the housing body 1. The housing body 1 is provided with at least two sets of insertion holes 17, and the handle 4 is provided with an elastic pin 41, which can be inserted into any set of insertion holes 17.

[0094] Specifically, by setting mutually cooperating elastic pins 41 and two or more sets of insertion holes 17, the handle 4 can be positioned in two or more different positions, thereby improving the flexibility of use of the handle 4 and its applicability to different application scenarios.

[0095] In one embodiment, such as Figures 15 to 18 As shown, the handle 4 includes a grip 42 and two handle arms 43 disposed at both ends of the grip 42. The grip 42 is located above the cover 2. The two handle arms 43 are respectively hinged to the two sides of the body 1. Both handle arms 43 are provided with elastic pins 41.

[0096] In one embodiment, such as Figures 15 to 18 As shown, there are three sets of insertion holes 17, one of which is for non-standard use. In this set of insertion holes 17, the handle 42 is positioned away from the second mounting bracket 14. In this state, the cover 2 can be moved up and down and rotated to open (in the process of opening the cover 2, the handle 4 needs to be removed from...). Figure 1 The state becomes Figure 7 and Figure 8 The first set of ports 17 is in the normal operating state; the other two sets are in the conventional operating state. In these two sets of ports 17, the handle 42 is positioned on the side closer to the second mounting bracket 14. In this state, the cover 2 cannot be rotated and opened, that is, the cover 2 cannot be switched to the open state. The above design can prevent the cover 2 from being opened accidentally, effectively improving the safety of the energy storage housing.

[0097] In one embodiment, the grip 42 is provided with a support slot and an elastic clamping structure for fixing a handheld power device, such as a mobile phone or tablet computer. Two sets of plug holes 17 in conventional use allow the handheld power device to be fixed at different angles, thereby improving the flexibility of the energy storage housing.

[0098] In one embodiment, a first interface is provided within the bracket slot for connecting a handheld power device, and a second interface is provided on the side wall of the housing body 1 for connecting an energy storage unit inside the energy storage housing. A wire groove is provided on the handle 43 located on the same side as the second interface. One end of the wire groove communicates with the bracket slot, and the other end extends to the hinge axis between the handle 43 and the housing body 1. The wire groove contains a connecting wire, one end of which connects to the first interface, and the other end connects to the second interface. This design improves the convenience of powering the handheld power device.

[0099] This embodiment also provides an energy storage device, which includes the above-described energy storage housing and an energy storage unit installed inside the energy storage housing.

[0100] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
