A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0036] In an embodiment of the present invention, a flip-top structure 10 for an energy storage power supply interface, a housing assembly, and an energy storage power supply are provided. The energy storage power supply includes a housing assembly, a power module, and an interface 30. The housing assembly further includes the flip-top structure 10 for the energy storage power supply interface and a housing 20. The housing 20 has at least one opening 22 defined therein. The interface 30 is inserted into the opening and secured to the opening 22 using a method not limited to bolts or threads. The interface 30 can be any suitable interface, such as a USB interface, and is not specifically limited herein. The interface 30 is electrically connected to the power module located within the housing 20. The flip-top structure 10 for the energy storage power supply interface is movably connected to the housing 20 and engages with the housing 20. The flip-top structure 10 for the energy storage power supply interface can block or open at least one interface 30.

[0037] refer to Figures 1-8As shown, the flip cover structure 10 of the energy storage power supply interface includes a cover body 11 and a flap 12. The first end of the cover body 11 is rotatably connected to the housing 20. For example, the cover body 11 and the housing 20 are rotatably connected via a first rotating shaft (not shown in the figure). A first elastic member 13 is provided between the cover body 11 and the housing 20. The first elastic member 13 provides elastic force to the cover body 11, so that the second end of the cover body 11, which is opposite to the first end, maintains a tendency to flip away from the housing 20. The flap 12 is rotatably connected to the second end of the cover body 11. For example, the flap 12 and the cover body 11 are rotatably connected via a second rotating shaft (not shown in the figure). The housing 20 is provided with a second clamping portion 21, and the flap 12 is provided with a first clamping portion 125. The flap 12 is engaged with the housing 20 through the first clamping portion 125 and the second clamping portion 21. Exemplarily, the first clamping portion 125 is a female snap and the second clamping portion 21 is a male snap. It is understandable that the first clamping portion 125 may be a male buckle, and the second clamping portion 21 may be a female buckle.

[0038] The flip cover structure 10 of the energy storage power supply interface is disposed on the first engaging portion 125 of the housing 20, which engages with the flip cover 11. This allows the cover body 11, when the interface 30 is closed, to tightly engage the housing 20, reducing the possibility of water entering the interface 30. The provision of the first elastic member 13 maintains a certain angle between the flip cover structure 10 of the energy storage power supply interface and the housing 20, making the plug-in operation more convenient and effectively protecting against rain, ensuring that functional components within the housing assembly, such as the power module, are not damaged by rain due to the opening of the interface 30. For example, under the action of the first elastic member 13, the angle between the flip cover structure 10 of the energy storage power supply interface and the housing 20 is maintained at 90°, that is, the cover body 11 is maintained in a perpendicular position relative to the housing 20. This allows the flip cover structure 10 of the energy storage power supply interface to maintain its shielding function while not affecting the normal use of the interface 30 connected to the power module. Of course, the angle between the flip cover structure 10 of the energy storage power supply interface and the housing 20 may also be less than 90°, so that water can flow along the flip cover structure 10 of the energy storage power supply interface to the ground.

[0039] Furthermore, the flip cover structure 10 of the energy storage power supply interface described above separates the traditional integrated flip cover, separating the portion that engages with the housing 20 to form a separate flap 12. To open the interface 30, the user simply applies an upward force to the flap 12 away from the housing 20. This force only needs to overcome the weight of the flap 12 and the engagement force between the first engaging portion 125 and the second engaging portion 21. Compared to an integrated flip cover, the required force is relatively small. Furthermore, once the first engaging portion 125 disengages from the second engaging portion 21, the cover body 11 automatically springs open due to the elastic potential energy accumulated by the first elastic member 13, eliminating the need for the user to continue flipping the cover body 11. This facilitates operation and creates a sense of power and technology. It is worth noting that the flip cover structure 10 of the energy storage power supply interface and the housing 20 may wear out due to frequent opening and closing, and the first engaging portion 125 is easily damaged. The separate design of the flap 12 and the cover body 11 allows for independent replacement of the flap 12 after damage to the first engaging portion 125, reducing subsequent maintenance costs.

[0040] In one embodiment, at least one side of the cover body 11 facing the housing 20 is elastic, so when the flip cover structure 10 of the energy storage power supply interface blocks the interface 30, the cover body 11 is squeezed and deformed, thereby achieving a better sealing effect on the interface 30. Figure 4 As shown, the cover body 11 includes a cover body main body 111 and a sealing portion 112. The sealing portion 112 is disposed on the side of the cover body main body 111 facing the housing 20. The sealing portion 112 is elastic. The cover body main body 111 is harder than the sealing portion 112 to improve the structural strength of the cover body 11, thereby extending the service life of the cover body 11. For example, the sealing portion 112 is made of a soft rubber material, while the cover body main body 111 is made of a hard rubber material.

[0041] More specifically, refer to Figure 3 As shown, the sealing portion 112 is hollowed out to reduce the weight of the cover body 11. An annular sealing frame is formed at the position of the sealing portion 112 corresponding to the interface 30. The area of ​​the sealing frame is larger than the area of ​​the interface 30. When the flip cover structure 10 of the energy storage power supply interface blocks the interface 30, the sealing frame is arranged around the outer periphery of the interface 30 and blocks the gap between the cover body 111 and the shell 20.

[0042] To enhance aesthetics, the first rotating shaft connecting the cover body 11 and the housing 20 and the first elastic member 13 are both disposed within the cover body 11. For this purpose, a first accommodating groove 113 is provided on the side of the cover body 11 facing the housing 20. A first shaft seat 115 is disposed within the first accommodating groove 113. The first shaft seat 115 has a first shaft hole for the first rotating shaft to pass through, and a second shaft seat 23 is provided on the housing 20 corresponding to the first shaft seat 115. The second shaft seat 23 has a second shaft hole for the first rotating shaft to pass through. The first rotating shaft passes through the first shaft seat 115 and the second shaft seat 23, respectively, to achieve a rotational connection between the cover body 11 and the housing 20. The first elastic member 13 is sleeved on the first rotating shaft. For example, the first elastic member 13 is a torsion spring, the first rotating shaft is a steel shaft, and the first rotating shaft is connected to the flap 12 and the cover body 11 by cold pressing.

[0043] More specifically, based on the requirement of sealing the docking interface 30, the first accommodating groove 113 is arranged outside the sealing frame, that is, for the sealing portion 112, the sealing portion 112 also includes a first accommodating frame arranged at the first end of the sealing frame, and the cover body 111 blocks the side of the first accommodating frame facing away from the shell 20 to form the first accommodating groove 113.

[0044] To further reduce the difficulty of opening the flip cover structure 10 of the energy storage power supply interface, the volume of the flap 12 is smaller than that of the cover body 11. Also for aesthetic reasons and sealing, the second end surface of the cover body 11 is recessed to form a second accommodating groove 114. Two opposing sidewalls of the second accommodating groove 114 are each provided with a third mounting hole. A third axle seat 123 is provided on the flap 12 corresponding to the third mounting hole. The third axle seat 123 is provided with a fourth mounting hole. The second rotating shaft passes through the third and fourth mounting holes to achieve a rotational connection between the flap 12 and the cover body 11. Specifically, the third axle seat 123 is provided on the cover body 111.

[0045] In one embodiment, the flip cover structure 10 of the energy storage power supply interface further includes a second elastic member 14 disposed between the flap 12 and the cover body 11. The second elastic member 14 provides elastic force to the flap 12, causing the first engaging portion 125 to disengage from the second engaging portion 21. Upon removal of the external force, the flap 12 automatically returns to a preset initial position, thereby maintaining relative stability between the flap 12 and the cover body 11 and preventing the flap 12 from rotating freely relative to the cover body 11. Specifically, to improve aesthetics, reduce the space occupied by the flap 12, and reduce the force applied when the flap 12 is engaged with the housing 20, when the flap 12 is in the preset initial position, its surface facing away from the housing 20 is flush with the surface of the cover body 11 facing away from the housing 20.

[0046] In one embodiment, the second elastic member 14 is a compression spring that extends in a direction perpendicular to the second rotating shaft, that is, in a direction perpendicular to the rotation axis of the flap 12. Of course, the second elastic member 14 may also be a torsion spring, which will not be described in detail here. More specifically, a first connecting portion 116 is provided on the bottom wall of the second accommodating groove 114 of the cover body 11, and a second connecting portion 124 is provided on the side of the flap 12 facing the bottom wall of the second accommodating groove 114. The two ends of the compression spring are respectively mounted on the first connecting portion 116 and the second connecting portion 124. Compared to a torsion spring, a compression spring can be replaced without removing the second rotating shaft, thereby reducing the subsequent maintenance costs of the flip cover structure 10 and the shell assembly of the energy storage power supply interface.

[0047] To facilitate force application, the flap 12 includes a flap body 121 and a force-applying portion 122. The flap body 121 is connected to the cover body 11. The force-applying portion 122 protrudes from the end connected to the flap body 121 toward the side away from the cover body 11, making it easy to grasp and thus facilitate force application. It is worth noting that when the flap 12 is in the preset initial position, the flap body 121 is located within the second receiving groove 114.

[0048] In order to further improve the sealing performance, a sealing member 40 is sleeved on the interface 30 , and the interface 30 cooperates with the housing 20 to squeeze the sealing member 40 to form a seal.

[0049] Specifically, refer to Figure 7 and Figure 8 As shown, the interface 30 includes an interface body 31 and a stopper 32. The interface body 31 is inserted into the opening 22 and electrically connected to the power module in the housing assembly. The interface body 31 is provided with an electrical connector. The stopper 32 is provided at the end of the interface body 31 and is located outside the housing assembly. The seal 40 is mounted on the interface body 31 and tightly abuts the housing 20 and the stopper 32. The seal 40 is not limited to a silicone seal ring.

[0050] The cover 11 of the energy storage power supply described above serves as the primary layer of protection, while the seal 40 serves as the secondary layer. These effectively isolate water from the power supply during adverse conditions such as disaster relief or heavy rain, particularly when water reaches the interface 30. The combined protection provided by the seal 112 on the cover 11 and the seal 40 has proven to achieve an IP66 rating for water and dust resistance, effectively withstanding various harsh environments and ensuring normal operation of the power supply under load.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
