Description

Technical Field

[0001] This application relates to the technical field of energy storage devices, and more specifically, to an energy storage power supply. Background Art

[0002] In related technologies, the flip structure usually adopts a hardware rotating shaft structure or a silicone hanging ear structure. However, the hardware rotating shaft structure usually has multiple parts, and some parts are small in volume, difficult to assemble, not easy to replace, and are prone to loss or omission during disassembly and assembly, and the cost is relatively high. The silicone hanging ear structure uses two-color injection molding, with poor stability. During the production process, the tightness has a large tolerance difference due to injection molding reasons. The product relies on multi-glue interference biting, resulting in very high requirements for the control of dimensional tolerances during molding. The flipping and closing feelings of the materials produced in the same batch are completely different due to the slight differences in tolerances, thus affecting the customer experience. Summary of the Utility Model

[0006] A flip, which includes a cover plate and two rotating shafts. The cover plate corresponds to the receiving groove. The two rotating shafts are arranged on the side surface of the cover plate and are rotatably connected to the two rotating holes. When the flip rotates, it has an open state in which the receiving groove is exposed and a closed state in which the receiving groove is covered. In the closed state, the flip is snap-connected to the body, and the rotating shafts can slide relative to the rotating holes to reduce the snap force between the flip and the body.

[0007] In the energy storage power supply provided in the embodiment of this application, both the body and the flip of the flip assembly are integrally processed and formed, effectively reducing the number of parts, and the parts are large in volume and simple to assemble, which is beneficial to reducing the difficulty of maintenance and replacement of the flip assembly.

[0014] In some embodiments, the density of the second reinforcing ribs is greater than that of the first reinforcing ribs.

[0015] In this way, since the stress received at the transfer portion is greater than that of the cover plate, the density of the reinforcing ribs on the transfer portion is greater than that of the reinforcing ribs on the cover plate, which is beneficial to further improving the structural strength of the transfer portion.

[0016] In some embodiments, the flip cover further includes a first positioning member, the first positioning member is arranged on the cover plate, the first positioning member is located on the side of the rotating shaft away from the cover plate, the main body further includes a second positioning member that can be snap-connected with the first positioning member, and when the first positioning member is snap-connected with the second positioning member, the cover plate is positioned in the open state.

[0024] In some embodiments, the rotating hole is a rectangular hole or an oval hole.

[0025] In this way, the rectangular hole or the oval hole can enable the flip cover to sink a certain distance after rotation, thereby assisting in fixing the flip cover.

[0038] In the related art, the flip structure usually adopts a hardware rotating shaft structure or a silicone ear-hanging structure. However, the hardware rotating shaft structure usually has multiple parts, and some parts are relatively small in volume, difficult to assemble, not easy to replace, and are prone to be lost or omitted during disassembly and assembly, and the cost is relatively high. The silicone ear-hanging structure adopts two-color injection molding, with poor stability.

The flip and close feelings of the materials produced in the same batch are completely different due to the slight difference in tolerances, thus affecting the customer experience.

[0039] Please refer to Figure 1 , an embodiment of the present application provides an energy storage power supply, and the energy storage power supply includes a flip assembly 100. The flip assembly 100 includes a body 10 and a flip 20. A receiving groove 11 is formed on the body 10, and two opposite rotation holes 111 are formed on the side surface of the receiving groove 11; the flip 20 includes a cover plate 21 and two rotating shafts 22. The cover plate 21 corresponds to the receiving groove 11. The two rotating shafts 22 are arranged on the side surface of the cover plate 21 and are rotatably connected to the two rotation holes 111. When the flip 20 rotates, it has an open state in which the receiving groove 11 is exposed and a closed state in which the receiving groove 11 is covered. In the closed state, the flip 20 is snap-connected to the body 10, and the rotating shaft 22 can slide relative to the rotation hole 111 to reduce the snap force between the flip 20 and the body 10.

[0040] In the energy storage power supply provided in the embodiment of the present application, the body 10 and the flip 20 of the flip assembly 100 are integrally processed and formed, effectively reducing the number of parts, and the parts are large in volume and simple to assemble, which is beneficial to reducing the difficulty of maintenance and replacement of the flip assembly 100. The kidney-shaped hole 111 rotation hole can make the flip 20 sink a certain distance after rotation, thereby assisting in fixing the flip 20; and both the body 10 and the flip 20 are injection-molded at one time, and no deformation will occur during the production process, which is beneficial to improving the finished product quality of the product.

[0041] Specifically, an energy storage power supply is a device that can store electrical energy and release it when needed. Its main function is to provide a stable and reliable power supply. When the system needs to store electrical energy, the controller charges the battery pack, and the battery pack converts the electrical energy into chemical energy for storage. When the system needs to use electrical energy, the controller first converts the DC electrical energy stored in the battery pack into AC electrical energy and then outputs it.

[0042] In the embodiment of the present application, the flip cover assembly 100 is arranged on the energy storage power supply, and the body 10 serves as a decorative cover of the energy storage power supply. Among them, the body 10 is an integrally formed one-piece structure, and the flip cover 20 is also an integrally formed one-piece structure.

[0043] In the embodiment of the present application, the outer surface of the body 10 is arc-shaped. On the one hand, the arc-shaped outer surface can make the body 10 look more beautiful. On the other hand, the arc-shaped outer surface can also improve the structural strength of the body 10. Similarly, the whole flip cover 20 is also arc-shaped, and the radian of the outer surface of the flip cover 20 is the same as that of the body 10.

[0044] In the embodiment of the present application, the accommodation groove 11 is arranged in the middle of the body 10. The middle part of the body 10 is recessed inward to form the accommodation groove 11. The inside of the accommodation groove 11 is used to install the control module and the connection port. Among them, the control module is used to control the energy storage power supply, and the connection port is used to supply power to external electrical equipment.

[0045] Furthermore, a sunken groove is provided at the edge of the opening of the accommodation groove 11. The sunken groove is arranged in a ring along the edge of the accommodation groove 11. When the flip cover 20 is closed, the cover plate 21 of the flip cover 20 sinks into the sunken groove, so that the surface of the flip cover 20 away from the accommodation groove 11 is flush with the surface of the body 10 where the accommodation groove 11 is provided, thereby making the flip cover assembly 100 more beautiful.

[0046] In some embodiments, a heat dissipation part is also provided on the body 10. A plurality of heat dissipation openings are arranged on the heat dissipation part in a grid distribution. A spoiler is arranged at each heat dissipation opening, and the spoilers arranged at each heat dissipation opening all face the same direction.

[0047] In some embodiments, the flip cover 20 is configured to be deformed under an external force to shorten the distance between the two rotating shafts 22. The flip cover 20 is also configured to, when the external force is removed, the two rotating shafts 22 extend into the two rotating holes 111, so that the cover plate 21 is rotatably connected to the body 10.

[0048] In this way, the flip connection between the body 10 and the flip cover 20 is realized through the elastic deformation of the flip cover 20, which is beneficial to reducing the difficulty of maintenance and replacement of the flip cover 20 assembly.

[0049] In the embodiments of the present application, to meet the deformation requirements of the flip cover 20, the main body 10 is usually made of organic polymer materials such as polycarbonate. As a polymer material, polycarbonate is commonly used in the outer casings of energy storage devices. It has properties such as light weight, high strength, corrosion resistance, and insulation, and is suitable for large-scale production with significant production efficiency and cost advantages. In terms of color and appearance, polycarbonate also has good performance and can be customized in appearance and color according to customer requirements. In addition, due to its light weight, polycarbonate has good seismic resistance. Similarly, the flip cover 20 is also made of organic polymer materials such as polycarbonate.

[0050] In the embodiments of the present application, the flip cover 20 is rotationally connected to the main body 10 by inserting the rotating shaft 22 into the rotating hole 111. To facilitate the insertion of the rotating shaft 22 into the rotating hole 111, a guiding inclined surface is provided on the side of the rotating shaft 22 away from the flip cover 20.

[0051] In other embodiments, the main body 10 and the flip cover 20 can also be made of other materials, such as aluminum alloy and stainless steel. Among them, aluminum alloy is one of the most commonly used outer casing materials at present. It has advantages such as light weight, corrosion resistance, electrical conductivity, and thermal conductivity. The surface of the aluminum alloy outer casing can be treated by anodic electroplating or spraying to further improve its corrosion resistance and aesthetic appearance. In addition, aluminum alloy is easy to process and form, and is suitable for large-scale production. However, its strength is relatively low and it may not be suitable as a component that needs to withstand large external forces. Stainless steel is also a commonly used outer casing material, with advantages such as high strength and corrosion resistance. There are many types of stainless steel materials, and the commonly used ones are 304 stainless steel and 316 stainless steel. Among them, 304 stainless steel has excellent corrosion resistance and processability and is relatively affordable, while 316 stainless steel is more corrosion-resistant and suitable for use in harsh environments. However, stainless steel is heavier and the processing difficulty is slightly higher, so the production cost is relatively high.

[0052] Please refer to Figure 2 and Figure 3 , in certain embodiments, the accommodation groove 11 includes a transfer groove 112. The transfer groove 112 has two oppositely arranged side walls 1121, and two rotating holes 111 are respectively arranged on the two side walls 1121. The cover plate 21 includes a transfer portion 211. The transfer portion 211 is arranged at the position of the cover plate 21 corresponding to the transfer groove 112, and two rotating shafts 22 are respectively arranged at both ends of the transfer portion 211.

[0053] In this way, the main body 10 and the flip cover 20 are rotationally connected through the transfer groove 112 and the transfer portion 211, which is beneficial to reducing the assembly difficulty of the main body 10 and the flip cover 20.

[0054] Specifically, the transfer groove 112 is arranged on one side of the accommodation groove 11 close to the rotating shaft 22. In the embodiment of the present application, the transfer groove 112 is actually a window opened on the body 10. Two oppositely arranged side walls 1121 are respectively arranged on both sides of the window along the axial direction of the rotating shaft 22. One end of each of the two oppositely arranged side walls 1121 is connected to the outer side wall 1121 of the accommodation groove 11, and the other end is connected to the bottom surface of the body 10.

[0055] Furthermore, the transfer groove 112 and its two oppositely arranged side walls 1121 are both integrally formed with the body 10 as an integral structure.

[0056] A transfer portion 211 extends outward near the transfer groove 112 of the cover plate 21. Support plates are formed at both ends of the transfer portion 211, and a rotating shaft 22 is formed on the support plates. The two rotating shafts 22 are arranged back to back. During installation, the two rotating shafts 22 arranged back to back are respectively inserted into two rotating holes 111 on the two oppositely arranged side walls 1121. The two rotating shafts 22 and the two rotating holes 111 are respectively in transition fit or clearance fit, so that the cover plate 21 can rotate better.

[0057] It is easy to understand that since the cover plate 21 needs to insert the transfer portion 211 into the transfer groove 112 and insert the rotating shaft 22 into the rotating hole 111 during installation, the length of the transfer portion 211 along the axial direction of the rotating shaft 22 should be slightly less than the length of the transfer groove 112 along the axial direction of the rotating shaft 22, and the distance between the ends of the two rotating shafts 22 should be slightly greater than the distance between the two side walls 1121. Furthermore, when the cover plate 21 rotates, the transfer portion 211 will rotate in the transfer groove 112, so the width of the transfer portion 211 should be slightly less than the width of the transfer groove 112.

[0058] Furthermore, the support plate is perpendicular to the transfer portion 211, and the edge of the support plate on the side away from the transfer portion 211 is arc-shaped, so as to avoid interference of the support plate when the cover plate 21 rotates. The rotating shaft 22, the support plate, the transfer portion 211 and the cover plate 21 are also integrally formed as an integral structure.

[0059] Please refer to Figure 2 , in some embodiments, the cover plate 21 further includes a cover body 23. The transfer portion 211 is located on one side of the cover body 23. First reinforcing ribs 231 and second reinforcing ribs 2111 are respectively arranged on the surfaces of the cover body 23 and the transfer portion 211 facing the accommodation groove 11.

[0060] In this way, the setting of the first reinforcing ribs 231 and the second reinforcing ribs 2111 is beneficial to improving the structural strength of the flip cover 20.

[0061] Specifically, the reinforcing rib, also known as the stiffener, refers to the raised or sunken part arranged along a certain direction on the surface of the structure or component, which is used to increase the strength and stability of the structure.

[0062] It should be noted that when setting the first reinforcing rib 231 and the second reinforcing rib 2111, multiple factors need to be comprehensively considered to ensure their effectiveness and the structural stability. The first reinforcing rib 231 and the second reinforcing rib 2111 should span the entire structure as much as possible to give full play to their strengthening effects. The first reinforcing rib 231 and the second reinforcing rib 2111 should be arranged along the line of force, and the number and position of the ribs are determined according to the magnitude and direction of the loads borne by different parts.

[0063] In addition, ribs should be added at the weak points of the structure, such as joints and corners, etc. The first reinforcing rib 231 and the second reinforcing rib 2111 should be avoided being arranged at the positions where there are connecting parts such as bolts and rivets, so as not to affect the strength of the connecting parts.

[0064] The thickness of the first reinforcing rib 231 and the second reinforcing rib 2111 should be less than the wall thickness of the product's outer shape to prevent defects such as shrinkage holes and indentations in the plastic part. The edges of the first reinforcing rib 231 and the second reinforcing rib 2111 should be polished to avoid generating micro-cracks or oxide layers, which will affect the service life of the ribs.

[0065] The directions of the first reinforcing rib 231 and the second reinforcing rib 2111 should be consistent with the demolding direction for easy demolding. The setting directions of the first reinforcing rib 231 and the second reinforcing rib 2111 should also be consistent with the direction of the melt flow during mold filling, which is beneficial to mold filling and forming, and avoids the melt flow being disturbed resulting in a reduction in the toughness of the plastic part. At the corners of plastic products, except when sharp corners are required in use, arc transitions should be adopted to improve strength, enhance aesthetics, and facilitate the flow of the melt during mold filling. The processing of the first reinforcing rib 231 and the second reinforcing rib 2111 should ensure accuracy and product quality, and avoid problems such as uneven rib fins, skew, or inconsistent spacing. The first reinforcing rib 231 and the second reinforcing rib 2111 should be evenly distributed at appropriate positions of the structure or product, and avoid problems such as too many or too few rib fins and uneven distribution.

[0066] In the embodiment of the present application, the first reinforcing rib 231 and the second reinforcing rib 2111 have the same thickness, and both the first reinforcing rib 231 and the second reinforcing rib 2111 are distributed in a grid pattern. Some of the second reinforcing ribs 2111 are connected to the support plate to enhance the structural strength of the support plate.

[0067] In other embodiments, the first reinforcing rib 231 and the second reinforcing rib 2111 can also be set in other distribution patterns, such as honeycomb distribution.

[0068] In some embodiments, the density of the second reinforcing rib 2111 is greater than the density of the first reinforcing rib 231.

[0069] In this way, since the stress on the transition portion 211 is greater than that on the cover plate 21 , the density of the reinforcing ribs on the transition portion 211 is greater than that on the cover plate 21 , which is beneficial to further improve the structural strength of the transition portion 211 .

[0070] Specifically, in this embodiment, the second reinforcing ribs 2111 provided on the transition portion 211 require a higher density due to their higher requirements for bearing and transferring stress, which can be achieved by increasing the number of reinforcing ribs, reducing the spacing between reinforcing ribs, or increasing the cross-sectional size of the reinforcing ribs.

[0071] In contrast, the density of the first reinforcing ribs 231 on the cover plate 21 can be relatively low because it mainly plays the role of enhancing the overall rigidity and stability. This can be achieved by reducing the number of reinforcing ribs, increasing the spacing between reinforcing ribs, or reducing the cross-sectional size of the reinforcing ribs. For example, the spacing between the first reinforcing ribs 231 can be set to twice the spacing between the second reinforcing ribs 2111, or the cross-sectional height of the first reinforcing ribs 231 can be set to 50% of the thickness of the cover plate 21, and the cross-sectional height of the second reinforcing ribs 2111 can be set to 80% of the thickness of the cover plate 21.

[0072] See also Figures 2 to 4 In some embodiments, the flip cover 20 also includes a first positioning member 24, which is disposed on the cover 21. The first positioning member 24 is located on the side of the rotating shaft 22 away from the cover 21. The body also includes a second positioning member 12 that can be snap-connected with the first positioning member 24. When the first positioning member 24 is snap-connected with the second positioning member 12, the cover 21 is positioned in an open state.

[0073] In this way, the first positioning member 24 and the second positioning member 12 cooperate to fix the opened flip cover 20, which is convenient for maintenance of the components inside the receiving slot.

[0074] Specifically, in the present embodiment of the application, after the flip cover 20 is opened, the first positioning member 24 rotates with the flip cover 20 and presses against the second positioning member 12. The second positioning member 12 is deformed so that the first positioning member 24 enters the second positioning member 12. The second positioning member 12 clamps the first positioning member 24 to fix the opened flip cover 20.

[0075] Furthermore, the first positioning member 24 and the cover plate 21 are an integral structure formed by integral processing. Rounded corners are provided on both sides of the first positioning member 24 to serve as a guide. The middle of the first positioning member 24 is hollow so that the thickness of the first positioning member 24 is less than or equal to the thickness of the flip cover 20, thereby avoiding defects such as shrinkage holes and dents on the first positioning member 24 during processing.

[0076] Similarly, the main body 10 and the second positioning member 12 are also an integral structure formed by integral processing, and the second positioning member 12 is disposed between two oppositely disposed side walls 1121 of the adapter groove 112 .

[0077] In the embodiment of the present application, the number of the first positioning member 24 is one, and correspondingly, the number of the second positioning member 12 is also one.

[0078] In other embodiments, the number of first positioning members 24 may be multiple, and the multiple first positioning members 24 are arranged at intervals. Correspondingly, the number of second positioning members 12 may be multiple, and the second positioning members 12 and the first positioning members 24 are arranged one by one.

[0079] See also Figure 3 In some embodiments, the first positioning member 24 is columnar, and the second positioning member 12 includes two elastic arms 121 spaced apart from each other. The two elastic arms 121 clamp the first positioning member 12 so that the first positioning member 12 is snap-connected with the second positioning member 24 .

[0080] In this way, the two deformable elastic arms 121 are helpful to reduce the difficulty of inserting the first positioning member 24 .

[0081] Specifically, in the embodiment of the present application, the two elastic arms 121 are cantilevered and arranged on the outer side wall 1121 of the receiving groove 11, and are located in the adapter groove 112. The top ends of the two elastic arms 121 are arc-shaped, and the top openings of the two arcs are arranged opposite to each other, so that the maximum distance between the two elastic arms 121 is greater than the width of the first positioning member 24, and the minimum distance between the two elastic arms 121 is slightly less than the width of the first positioning member 24.

[0082] In the embodiment of the present application, two elastic arms 121 are provided. When the first positioning member 24 is engaged, the two elastic arms 121 are deformed at the same time and the openings are enlarged. This makes the elastic deformation of the two elastic arms 121 smaller, thereby avoiding the breakage or inability to recover of the elastic arms 121 caused by the larger deformation of the two elastic arms 121.

[0083] Furthermore, the thickness of the two elastic arms 121 is less than or equal to the thickness of the flip cover 20 , thereby preventing the two elastic arms 121 from having defects such as shrinkage holes and dents during processing.

[0084] In other embodiments, only one elastic arm 121 may be provided, and a fixing structure on the other side cooperates with the elastic arm 121 to fix the first positioning member 24 .

[0085] See also Figure 5, in some embodiments, the flip cover 20 further includes a buckle 25. The buckle 25 is disposed on a side of the cover plate 21 away from the rotating shaft 22. A clamping groove 13 that cooperates with the buckle 25 is provided on the body 10. The clamping groove 13 is disposed on a side wall 1121 of the accommodating groove 11 away from the rotating hole 111. When the flip cover 20 is in a closed state, the buckle 25 is in snap-fit with the clamping groove 13, and the flip cover 20 can slide along the rotating hole 111 to reduce the snap force between the buckle 25 and the clamping groove 13.

[0086] In this way, the cooperation between the buckle 25 and the clamping groove 13 can prevent the closed flip cover 20 from being accidentally opened by an external force.

[0087] Specifically, in this embodiment, the buckle 25 is U-shaped. One end of the buckle 25 is connected to the edge of the flip cover 20, and the other end is suspended.

[0088] Further, a clamping portion is provided on a side of the suspended end of the buckle 25 close to the side wall 1121 of the accommodating groove 11. The clamping portion protrudes outward. A clamping groove 13 is provided on the side wall 1121 of the accommodating groove 11 away from the rotating hole 111. The depth and size of the clamping groove 13 are slightly larger than those of the clamping portion, so that the clamping portion can be completely snapped into the clamping groove 13.

[0089] Further, the cross section of the clamping portion is trapezoidal to play a guiding role and facilitate the clamping portion to be snapped into the clamping groove 13.

[0090] In the embodiment of the present application, when the flip cover 20 is closed, the buckle 25 will be received into the accommodating groove 11, and the clamping portion abuts against the side wall 1121 of the accommodating groove 11, so that the U-shaped buckle 25 is deformed. When the flip cover 20 is completely closed, the clamping portion slides to the clamping groove 13 and slides into the clamping groove 13 to complete the locking.

[0091] In the embodiment of the present application, the numbers of both the buckle 25 and the clamping groove 13 are two, and the clamping grooves 13 and the buckles 25 are arranged in one-to-one correspondence.

[0092] In some embodiments, the number of the buckles 25 is multiple, and the multiple buckles 25 are arranged at intervals. Similarly, the number of the clamping grooves 13 is also multiple, and the clamping grooves 13 and the buckles 25 are arranged in one-to-one correspondence.

[0093] In some embodiments, the cross section of the clamping portion may also be in other shapes, such as triangular, semi-circular, semi-elliptical, etc.

[0094] Please refer to Figure 5 , in some embodiments, the flip cover 20 further includes a tongue 26. The tongue 26 is disposed on a side of the cover plate 21 away from the rotating shaft 22.

[0095] In this way, when the flip cover 20 is closed, the upturned tongue 26 can reduce the opening difficulty of the flip cover 20.

[0096] Specifically, in the embodiments of the present application, the flip cover 20 is convex upward in an arc shape to form a covering structure, and a hand-holding space is formed below the cover tongue 26 to facilitate the operator to insert the hand to open the flip cover 20.

[0097] Furthermore, all corners of the periphery of the cover tongue 26 are provided with transition rounded corners to prevent the operator from scratching the hand when opening the flip cover 20, and at the same time, it can also make the flip cover 20 more beautiful.

[0098] Furthermore, a concave avoidance groove 14 is also provided near the cover tongue 26 of the main body 10. The avoidance groove 14 and the space below the cover tongue 26 jointly enclose a hand-holding space to more easily accommodate the operator's hand. The setting of the avoidance groove 14 can prevent the cover tongue 26 from protruding outward too much, thus affecting the overall beauty of the cover plate 21, and at the same time, it can ensure that there is a sufficiently large hand-holding space.

[0099] In some embodiments, the rotation hole 111 is a rectangular hole or an oval hole.

[0100] In this way, the rectangular hole or the oval hole can make the flip cover sink a certain distance after rotation, thereby assisting in the fixation of the flip cover.

[0101] Specifically, the rotation hole 111 is a rectangular hole or an oval hole. In the embodiments of the present application, the rotation hole 111 is an oval hole, which is also called an oblong hole or a slotted hole, and is a special hole type. The oval hole can be flexibly adjusted according to the specific application scenario to adapt to different sizes and shapes of the rotating shaft 22. This makes the oval hole widely applicable in the manufacturing of the rotating shaft 22.

[0102] In the embodiments of the present application, the length direction of the oval hole is arranged along the length direction of the main body 10, so that the rotating shaft 22 has a certain dropping space during the flipping process of the cover plate 21, thereby allowing the cover plate 21 to be finely adjusted when needed to adapt to different installation environments or working requirements. This fine-tuning ability enables the cover plate 21 to more flexibly adapt to various application scenarios.

[0103] In addition, a certain dropping space can reduce the relative movement between the cover plate 21 and the installation surface, thereby reducing the degree of wear. This helps to extend the service life of the cover plate 21, reduce the replacement frequency and maintenance cost.

[0104] It should be noted that the oval hole needs to be pre-treated to ensure that the inside of the hole is flat, without burrs, notches, etc. This helps to improve the positioning accuracy of the parts and reduce friction. And during the processing of the oval hole, the process accuracy should be ensured to guarantee the positioning accuracy of the parts. During processing, excessive load should be avoided to prevent problems such as part deformation and unsmooth movement. When using the oval hole, it should be kept clean to prevent dust or debris from entering the hole and affecting the positioning accuracy of the parts.

[0105] In some embodiments, the through hole 111 is a rectangular hole, and the length direction of the rectangular hole is arranged along the length direction of the body 10, so that the rotating shaft 22 has a certain dropping space during the flipping process of the cover plate 21.
