[0021] Please see Figures 1-5 , Figure 1 This is a partial perspective view of the energy storage power supply 100 according to an embodiment of the present invention, showing the cover plate 30 in the open position.

[0022] The energy storage power supply 100 of this application embodiment includes a housing 10, a connection port 20, and a cover plate 30. The housing 10 is provided with an abutment portion 11; the connection port 20 is disposed on the housing 10; the cover plate 30 includes a plate body 31 and a protrusion 32 connected to the edge of the plate body 31. One of the cover plate 30 and the housing 10 is provided with a transition hole 12, and the other is provided with a rotating shaft 33. The cover plate 30 rotates between an open position and a closed position by cooperating with the transition hole 12 through the rotating shaft 33. When the cover plate 30 is in the closed position, it covers the connection port 20. When the cover plate 30 is in the open position, the protrusion 32 abuts against the abutment portion 11 to keep the cover plate 30 in the open position.

[0023] In this embodiment of the energy storage power supply 100, the protrusion 32 of the cover plate 30 abuts against the contact portion 11 of the housing 10. The protrusion 32 and the contact portion 11 are held in the open position by friction, upward force and other forces, so that the cover plate 30 is exposed without the need to hold the cover plate 30 by hand, thereby facilitating the insertion operation with the connection port 20.

[0024] Specifically, the energy storage power supply 100 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 battery pack converts the electrical energy into chemical energy for storage; when the system needs to use electrical energy, the DC electrical energy stored in the battery pack is converted into AC electrical energy and then output.

[0025] The housing 10 protects the components inside the energy storage power supply 100 and improves the ease of use of the energy storage power supply 100. The housing 10 can be integrally molded by injection molding to allow for different appearance shapes, improving the aesthetics of the energy storage power supply 100. The abutting portion 11 of the housing 10 is a component of the housing 10, and the abutting portion 11 can also be formed by injection molding.

[0026] In one example, the housing 10 can be made of organic polymer materials such as polycarbonate. Polycarbonate, as a polymer material, is commonly used for the outer shell of energy storage devices. It possesses properties such as lightweight, high strength, corrosion resistance, and insulation, making it suitable for large-scale production with significant advantages in production efficiency and cost. Polycarbonate also performs well in terms of color and appearance, allowing for customization of appearance and color according to customer needs. Furthermore, due to its lightweight nature, polycarbonate has good shock resistance. Similarly, the cover plate 30 is also made of organic polymer materials such as polycarbonate.

[0027] Connection port 20 is, for example, a charging / discharging port, such as a USB port. The energy storage power supply 100 can be charged and discharged through connection port 20.

[0028] The cover plate 30 serves as a covering element and can be made of flexible parts such as silicone to achieve the effect of covering and sealing. The cover plate 30 may be provided with a rotating shaft 33, and the housing 10 may be provided with a connecting hole 12. The rotating shaft 33 is rotatably disposed in the connecting hole 12, thereby allowing the cover plate 30 to be rotatably disposed on the housing 10.

[0029] In one example, the cover plate 30 is flipped from bottom to top to rotate from the closed position to the open position. After the cover plate 30 is flipped upward, the end face of the protrusion 32 and the end face of the abutment 11 abut against each other. The force exerted by the abutment 11 on the protrusion 32 has an upward component force. Under the action of friction, the upward component force of the abutment 11 on the protrusion 32, and other forces, the cover plate 30 remains in the open position, so that the user does not need to hold the cover plate 30 and can easily hold the external plug-in device to plug into the connection port 20.

[0030] Please see Figures 3-5 In some embodiments, the housing 10 is provided with a transition groove 13, and an abutment portion 11 is provided on the bottom surface of the transition groove 13. When the cover plate 30 is in the closed position, the protrusion 32 is at least partially received in the transition groove 13.

[0031] Thus, the adapter groove 13 allows the protrusion 32 to rotate with the housing 10. The protrusion 32 is at least partially housed in the adapter groove 13, giving the protrusion 32 room to rotate, which is beneficial for the cover 30 to be flipped so that it can rotate back and forth between the closed and open positions.

[0032] Specifically, the adapter groove 13 can be formed by recessing the outer surface of the housing 10 inward, or by providing a protrusion or other structure on the outer surface of the housing 10, or a combination of both. The bottom surface of the adapter groove 13 is the inner surface facing upward.

[0033] Please see Figures 3-5 In some embodiments, the abutment portion 11 includes a connecting arm 111 and an abutment arm 112 extending from the connecting arm 111 to the outside of the housing 10. The abutment arm 112 has a first arcuate surface 113 at one end away from the connecting arm 111, and the protrusion 32 has a second arcuate surface 321. When the cover plate 30 is in the opening process and in the open position, the first arcuate surface 113 and the second arcuate surface 321 remain in contact with each other.

[0034] Thus, the first arc surface 113 and the second arc surface 321 cooperate, so that during the flipping process, the cover plate 30 rotates along the first arc surface 113 via the second arc surface 321, thereby rotating between the closed position and the open position. Since the arc surface is relatively smooth, the cover plate 30 rotates more smoothly, reducing adverse effects such as jamming during the rotation of the cover plate 30.

[0035] Specifically, the connecting arm 111 and the abutting arm 112 are connected in a bent shape. The free end of the abutting arm 112 faces the outside of the housing 10 and forms a first arcuate surface 113. The side of the protrusion 32 away from the plate 31 forms a second arcuate surface 321. The first arcuate surface 113 and the second arcuate surface 321 remain in contact during the rotation of the cover plate 30.

[0036] Please see Figure 4 , Figure 6 and Figure 7 In some embodiments, the second arcuate surface 321 has a height difference along the length direction of the protrusion 32, and there are two abutting portions 11 with a height difference, so that the corresponding parts of the first arcuate surface 113 and the second arcuate surface 321 match and abut.

[0037] Thus, when the cover 30 is in the closed position, the second arcuate surface 321 is located on the outer top side of the cover 30 and is at least exposed. The second arcuate surface 321 forms a height difference along the length of the protrusion 32, which can be matched with the housing 10 to form a specific appearance shape. On this basis, the two abutting parts 11 also form a height difference, so that the first arcuate surfaces 113 of the two grounding parts abut against the corresponding parts of the second arcuate surface 321 respectively, so that the cover 30 can remain in the open position after being opened.

[0038] Specifically, the length direction of the protrusion 32 is the length direction of the side edge of the protrusion 32 away from the plate 31, and the height of the second arc-shaped surface 321 can gradually decrease along the length direction of the protrusion 32.

[0039] Please see Figure 3 and Figure 4 In some embodiments, the side of the adapter groove 13 is provided with an adapter hole 12, and the protrusion 32 is provided with a rotating shaft 33, which is interference-fitted with the adapter hole 12.

[0040] Thus, the interference fit between the rotating shaft 33 and the adapter hole 12 creates a large frictional force between them, making the cover plate 30 more stable in the open position.

[0041] In one example, there are two pivots 33 and two adapter holes 12, with the two pivots 33 respectively located on opposite sides of the protrusion 32. When installing the cover plate 30, the plate body 31 can be made slightly parallel to each other so that the distance between the two pivots 33 is small, thus allowing it to fit into the adapter hole 12.

[0042] Please see Figure 1 and Figure 2 In some embodiments, the housing 10 is provided with a recess 14, and the connection port 20 is provided on the bottom surface of the recess 14. When the cover plate 30 is in the closed position, the plate 31 is at least partially inserted into the recess 14.

[0043] Thus, the plate 31 is at least partially inserted into the sink 14, allowing the plate 31 to form a seal with the sidewall of the sink 14, thereby providing good dust and water protection for the connection port 20 on the bottom surface of the sink 14. Specifically, the bottom surface of the sink 14 is the side of the cover plate 30 facing the plate 31 when it is in the closed position.

[0044] Please see Figure 2 , Figure 8 and Figure 9 In some embodiments, a buckle 34 is provided on the side of the plate 31 opposite to the protrusion 32, and the housing 10 is provided with a groove 15 that cooperates with the buckle 34. The groove 15 is connected to the recess 14. When the cover plate 30 is in the closed position, the buckle 34 is engaged with the groove 15.

[0045] Thus, the latch 34 and the slot 15 cooperate to prevent the closed cover 30 from being accidentally opened by external force. Specifically, in this embodiment, the latch 34 is U-shaped, with one end connected to the edge of the cover 30 and the other end suspended. In this embodiment, when the cover 30 is closed, the latch 34 is engaged in the slot 15, and the latch 34 abuts against the bottom wall of the slot 15, causing the U-shaped latch 34 to deform. When the cover 30 is fully closed, the latch 34 and the slot 15 are locked together.

[0046] In this embodiment, there are two buckles 34 and two slots 15, and the slots 15 and buckles 34 are set in a one-to-one correspondence.

[0047] In some embodiments, the cover 30 opens at an angle greater than 90 degrees. In other words, the cover 30 rotates more than 90 degrees from the closed position to the open position. For example, the opening angle of the cover 30 can be 110 degrees, 120 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, or 150 degrees. This larger opening angle of the cover 30 allows for full exposure of the connection port 20, facilitating the insertion of external devices into the connection port 20.

[0048] Please see Figure 1 , Figure 8 and Figure 9 In some embodiments, a handle structure 35 is provided on the side of the plate 31 opposite to the protrusion 32. This handle structure 35 facilitates the operator in opening the cover 30. Specifically, a recessed relief groove 351 is also provided on the plate 31 near the handle structure 35. The relief groove 351 and the lower part of the handle structure 35 together form a handhold space, making it easier to accommodate the operator's hand. The relief groove 351 prevents the handle structure 35 from protruding excessively, thus avoiding affecting the overall aesthetics of the cover 30, while also ensuring a sufficiently large handhold space.

[0049] like Figure 8 As shown, in some embodiments, when the cover plate 30 is in the closed position, the plate 31 is provided with a reinforcing rib 36 on the side facing the housing 10. In this way, the reinforcing rib 36 can increase the strength and stability of the plate 31, thereby reducing the deformation of the plate 31 and improving the covering and sealing effect of the plate 31.
