Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 3, in some embodiments, the present utility model provides an energy storage compartment 10, including a compartment body 12 and a compartment door 111, where the compartment body 12 has an opening 121, and the compartment door 111 is disposed at the opening of the compartment body 12 in a retractable manner. For example, in some embodiments, the door 111 is hinged to the body 12. The door 111 is stably switchable between an open state and a closed state with respect to the cabin 12, and a variable range of the door 111 with respect to the cabin 12 is maintained after a plurality of state switches.

Alternatively, in other embodiments, the door 111 may be snap-fit to the body 12, and the door 111 may be removed from the body 12 by disengaging the snap-fit. Or, the cabin door 111 and the cabin body 12 may be connected in other manners, so long as the cabin door 111 can be opened and closed at the opening of the cabin body 12.

As shown in fig. 8, the side surface of the cabin 12 surrounding the opening 121 is a surface a; the outer peripheral surface of the cabin door 111 is a B surface; the inner side surface 111 of the cabin door 111 facing the cabin body 12 is a C surface; the face of the door 111 opposite to the face C is the face D; the surface of the cabin 12, which is positioned at the opening, intersects with the surface A and faces the outside of the cabin 12, is the surface E.

In order to ensure that the energy storage compartment 10 meets the protection level requirements when the compartment door 111 is in the closed state, as shown in fig. 2 to 4, in some embodiments, a sealing fixing member 122 adapted to the periphery of the opening is disposed at the opening of the compartment body 12, and the sealing fixing member 122 is located in the compartment body 12. The energy storage compartment 10 further comprises a first seal 112, a second seal 113 and a third seal 13. The side of the door 111 facing the interior of the cabin 12 when the door 111 is in the closed state is the inner side 1111.

Further, as shown in fig. 7 and 10, the first seal 112 is disposed around the outer edge of the door 111, and the second seal 113 is attached to the door around the outer edge of the third seal 13. When the cabin door 111 is in a closed state, the first sealing member 112 is in abutting sealing between the cabin door 111 and the cabin body 12, the second sealing member 113 and the third sealing member 13 are in abutting sealing between the inner side 1111 of the cabin door 111 and the sealing fixing member 122, and the second sealing member 113 is located at the periphery of the third sealing member 13.

Under the multiple sealing actions of the first sealing element 112, the second sealing element 113 and the third sealing element 13, when the cabin door 111 is in the closed state, the protection level of the energy storage cabin 10 can meet the protection level requirement of energy storage equipment. Specifically, when the door 111 is in the closed state, the first seal 112 is sealed between the door 111 and the cabin 12 in an abutting manner, as a first protection. The second seal 113 seals against the inner side 1111 of the door 111 and the seal mount 122 as a second shield. The third seal 13 is sealed against the inner side 1111 of the door 111 and the seal holder 122 as a third protection.

Foreign matters such as dust and rainwater outside the energy storage cabin 10 can enter the energy storage cabin 10 only through the first protection, the second protection and the third protection in sequence, and the protection grade of the IP54 can be achieved through the first protection of the first sealing piece 112 under normal conditions, so that the protection grade requirement of a common container is met. The energy storage compartment 10 as the storage energy storage element has a protection level higher than that of a general container, so that a second protection and a third protection are further added.

Moreover, the second sealing member 113 and the third sealing member 13 are in abutting sealing connection with the cabin door 111 and the sealing fixing member 122 retracted in the cabin body 12, so that when the cabin door 111 is in a closed state, the second sealing member 113 and the third sealing member 13 are protected inside the cabin door 111, and the service lives of the second sealing member 113 and the third sealing member 13 are long.

Further, as shown in fig. 5 to 10, in some embodiments, when the door 111 is in the closed state, the door 111 is at least partially located in the opening 121 of the cabin 12, and the first seal 112 is at least partially sealed between the outer peripheral surface (i.e., the B-surface shown in fig. 8) of the door 111 and the side wall surrounding the opening 121 on the cabin 12. When the door 111 is in the closed state, the gap width between the B face and the cabin 12 is fixed, and the first sealing member 112 presses between the B face and the cabin 12, so that the sealing reliability is high.

In particular, the first seal 112 may be connected to the hatch 111, the first seal 112 being movable with the hatch 111 relative to the hatch 12; alternatively, the first sealing member 112 is connected to the cabin 12, and the relative position between the first sealing member 112 and the cabin 12 is unchanged during the door opening and closing process.

In some embodiments, as shown in fig. 6, 7, 8 and 10, the first seal 112 includes a fixed body portion 1121, a lip seal portion 1122, and a reinforcing seal portion 1123, the fixed body portion 1121 surrounds the outer peripheral surface (i.e., the B-surface shown in fig. 8) of the door 111, the lip seal portion 1122 is connected to the fixed body portion 1121, the reinforcing seal portion 1123 is connected to the fixed body portion 1121, and the first seal 112 follows the door 111 relative to the cabin 12 when the door 111 is opened relative to the cabin 12. The stationary body portion 1121 may be attached to the B-side by adhesion, screw attachment, or other means.

Further, as shown in fig. 7 and 10, a part of the lip seal 1122 extends toward one side of the fixed body portion 1121 facing the door 111 and overlaps the outer side surface of the door 111, and another part of the lip seal 1122 extends toward the other side of the fixed body portion 1121 and can overlap the cabin 12 when the door 111 is in the closed state. When the door 111 is in the closed state, the lip seal 1122 is located outside the door 111 and the cabin 12, and shields the gap between the door 111 and the cabin 12 from foreign matter.

As shown in fig. 7 and 8, the left part of the lip seal 1122 is overlapped on the D surface, the right part of the lip seal 1122 is overlapped on the E surface, and when the door is closed, the whole lip seal 1122 is pressed to form a straight line shape, and at this time, the left and right parts of the lip seal 1122 are not arched relative to the D surface and the E surface, and are subjected to elastic force to generate a tension force towards the outside of the door 111, thereby blocking the passage between the a surface and the B surface. In addition, the lip seal 1122 is configured to include left and right portions that overlap the D and E faces to ensure that both sides are stressed, preventing the entire lip seal 1122 from falling into the channel between the a and B faces when the entire lip seal 1122 is forced when either of the left and right portions is absent.

In the present preferred embodiment, as shown in fig. 7 and 8, the portion of the first seal 112 disposed in the passage between the a-side and the B-side is a structure (i.e., the main body portion 1121 and the reinforcing seal portion 1123) which exhibits a bent hook shape, and the direction of the bent hook arches toward the cabin 12 side, the surface of the bent hook-shaped portion on the cabin 12 side in the closed state of the door 111 is a first bent hook face, and the surface on the door 111 side is a second bent hook face, as seen in fig. 7, the deformation amount of the second bent hook face is larger than that of the first bent hook face, and since the foreign matter or moisture enters the cabin 12 from the door 111 side, the second bent hook face is provided with a larger deformation amount, which has the advantage of starting blocking at the side near moisture or foreign matter side, and has a more sealing effect than in the case where the second bent hook face is smaller.

The reinforcing seal 1123 is abutted and sealed between the outer peripheral surface of the door 111 and the cabin body 12 when the door 111 is in the closed state, and the reinforcing seal 1123 functions to further increase the sealing property. In some embodiments, as shown in fig. 7, a side edge of the reinforced sealing part 1123 is connected to the fixed body part 1121, the side edge of the reinforced sealing part 1123 connected to the fixed body part 1121 is a first side edge, a side edge of the reinforced sealing part 1123 opposite to the first side edge is a second side edge, and the reinforced sealing part 1123 has a tendency to bend toward the inside of the door 111 in a direction from the first side edge to the second side edge, so that the body part and the reinforced sealing part form the aforementioned hook shape. As shown in fig. 7 and 8, the reinforced sealing portion 1123 is capable of abutting against the surface a and gradually elastically deforming during the gradual closing of the door 111, the reinforced sealing portion 1123 is pressed by the door 111 and the body 12 to deform the maximum amount when the door 111 is closed, the bending degree of the reinforced sealing portion 1123 is the maximum, and the reinforced sealing portion 1123 recovers elastic deformation after the door 111 is opened. The first seal 112 including the fixed body portion 1121, the lip seal portion 1122, and the reinforcing seal portion 1123 can be reliably fitted not only to the door 111, but also has high sealing performance by the double action of the lip seal portion 1122 and the reinforcing seal portion 1123.

In fig. 6 to 8, the state of the door 111 shown by the broken line is an open state, and the state of the door 111 shown by the solid line is a closed state. When the hatch 111 is in the open condition, the first seal 112 moves with the hatch 111 out of engagement with the hatch body 12, while the left portion of the lip seal 1122 is always in contact with the D-face. When the door 111 is in the closed state, the reinforcing seal 1123 is sealed between the B-side and the a-side.

Further, as shown in fig. 3, 7 and 10, in some embodiments, the sealing fixing member 122 includes a fixing frame 1221, an outer ring of the fixing frame 1221 is connected to the cabin 12, an inner ring of the fixing frame 1221 is turned towards a side facing away from the cabin 12 to form a flange 1222, and the flange 1222 and the fixing frame 1221 together form a frame structure with a "J" shape in cross section. Thus, the fixing frame 1221 and the flange 1222 form a groove 1223, and a small amount of foreign matters such as dust or rainwater passing through the first protection are intercepted in the groove 1223 of the sealing fixing member 122, and a protection is added again, so that the protection level of the energy storage compartment 10 can reach the IP66.

The ring of grooves 1223 formed on the sealing and fixing member 122 can guide the intercepted foreign matters to the lower portion of the sealing and fixing member 122, and only the groove sections of the grooves 1223 located at the lower portion of the sealing and fixing member 122 need to be cleaned.

When the seal holder 122 includes the fixing frame 1221 and the flange 1222, as shown in fig. 7 and 9, when the door 111 is in the closed state, the second seal 113 is sealed between the inner side 1111 of the door 111 and the fixing frame 1221, and the third seal 13 is sealed between the inner side 1111 of the door 111 and the flange 1222. The cabin door 111 and the fixed frame 1221 are sealed by the second sealing member 113, and the cabin door 111 and the flange 1222 are sealed by the third sealing member 13. Foreign objects passing through the second pass protection are first caught in the groove 1223, and the non-caught foreign objects are further caught by the third pass protection to which the third seal 13 belongs, so that the energy storage compartment 10 is protected more highly.

In particular, in one embodiment, as shown in fig. 7 and 10, the flange 1222 is perpendicular to the direction in which the third seal 13 is pressed, in other words, the flange 1222 is perpendicular to the opening of the cabin 12, and when the cabin door 111 is in the closed state, the flange 1222 faces the inner side of the cabin door 111. The portion of the fixing frame 1221 that is in contact with the second sealing member 113 is perpendicular to the opening of the cabin 12, and the portion of the fixing frame 1221 faces the inner side of the cabin 111 when the cabin 111 is in the closed state.

In particular, in some embodiments, as shown in fig. 7, the second seal 113 is connected to the door 111, and the third seal 13 is connected to the seal holder 122, such as the third seal 13 is connected to the flange 1222. When the hatch 111 is opened, both the second seal 113 and the first seal 112 move with the hatch 111 relative to the hatch body 12, the third seal 13 being located on the seal holder 122.

In order to ensure that the second sealing member 113 seals the gap between the fixed frame 1221 and the door 111 when the door 111 is in the closed state, as shown in fig. 7, 8 and 10, in some embodiments, the inner side 1111 of the door 111 is provided with a ring of pressing members 114, and when the door 111 is in the closed state, the pressing members 114 are opposite to the fixed frame 1221, and the second sealing member 113 is mounted on a pressing portion 1141 of the pressing members 114 near the fixed frame 1221 and can abut against the fixed frame 1221. After the pressing piece 114 is additionally arranged, the distance between the pressing part 1141 and the fixed frame 1221 is smaller than the distance between the inner side 1111 of the cabin door 111 and the fixed frame 1221, and the second sealing piece 113 can be pressed on the fixed frame 1221 more tightly under the action of the pressing piece 114, so that the sealing reliability is improved.

Further, as shown in fig. 7 and 10, in some embodiments, the second sealing member 113 includes a second mounting portion 1131 and a second pressing sealing portion 1132 that are connected to each other, the second mounting portion 1131 is provided with a circle of second mounting grooves 1133, the top pressing portion 1141 is mounted in the second mounting grooves 1133, the second pressing sealing portion 1132 is located on a side of the top pressing portion 1141 facing away from the door 111, and the second pressing sealing portion 1132 can abut against the fixing frame 1221 when the door 111 is in the closed state. The second sealing member 113 is assembled to the pressing member 114 through the second mounting groove 1133, and the assembling reliability is high. And the second press seal 1132 mainly plays a role of sealing.

As shown in fig. 10, the second compression seal 1132 has a second cavity 1134 therein, and the second compression seal 1132 has an elastic deformation capability, wherein the second cavity 1134 is provided to improve the elastic deformation capability to some extent. When the second sealing member 113 is not abutted against the sealing fixing member 122, the second pressing sealing portion 1132 is in a stretched state, and the second cavity 1134 is larger. When the second seal 113 is pressed against the seal holder, the second pressing seal 1132 is elastically deformed, and the second cavity 1134 is reduced in volume.

Moreover, in some embodiments, as shown in fig. 7 and 10, when the door 111 is in the closed state, the pressing portion 1141 is perpendicular to a portion of the fixed frame 1221 for abutting against the second seal 113, and the pressing portion 1141 provides a force perpendicular to the foregoing portion of the fixed frame 1221 to the second pressing seal 1132, so that the second pressing seal 1132 is tightly pressed between the pressing portion 1141 and the fixed frame 1221.

In some embodiments, the pressing member 114 is a frame structure surrounding a circle, and the pressing portion 1141 is a plate structure having a cross-sectional shape corresponding to the shape of the second mounting groove 1133.

As shown in fig. 3 and 4, the pressing member 114, the second sealing member 113, the door 111, and the first sealing member 112 together constitute the door unit 11, and each feature included in the door unit 11 moves during opening and closing of the door 111 with respect to the cabin 12.

As shown in fig. 7 and 10, when the door 111 is in the closed state, the minimum distance between the pressing portion 1141 and the fixed frame 1221 is smaller than the maximum distance between the flange 1222 and the fixed frame 1221. The third sealing member 13 needs to be extruded between the flange 1222 and the inner side 1111 of the door 111, and the distance between the flange 1222 and the inner side 1111 of the door 111 is smaller than the distance between the fixed frame 1221 and the inner side 1111 of the door 111, so that the distance between the inner side 1111 of the door 111 and the fixed frame 1221 is necessarily larger, and based on the pressing member 114 added on the inner side 1111 of the door 111, the pressing member 114 extends to the inner side of the flange 1222, so that the gap width of the second sealing member 113 needs to be sealed is reduced, and the sealing reliability of the second sealing member 113 is higher.

Further, as shown in fig. 7 and 10, in some embodiments, the third sealing member 13 includes a first mounting portion 131 and a first extrusion sealing portion 132 that are connected to each other, the first mounting portion 131 is provided with a circle of first mounting grooves 133, the flange 1222 is mounted in the first mounting grooves 133, the first extrusion sealing portion 132 is located on a side of the first mounting portion 131 facing away from the interior of the cabin body 12, and the first extrusion sealing portion 132 can abut against the inner side 1111 of the cabin door 111 when the cabin door 111 is in the closed state. The third sealing member 13 is assembled on the flange 1222 through the first mounting groove 133, so that the assembly reliability is high, and the relative position between the third sealing member 13 and the cabin 12 is unchanged. The collar 1222 has a plate-like structure, and the collar 1222 is inserted into the first mounting groove 133.

As shown in fig. 10, the first compression seal 132 has a first cavity 134 therein, the first compression seal 132 has an elastic deformation capability, and the second cavity 1134 is capable of enhancing the elastic deformation capability of the first compression seal 132. When the first press seal 132 is not in contact with the door 111, the first press seal 132 is in a stretched state, and the first cavity 134 is large in volume. When the first press seal 132 is pressed against the door 111, the first press seal 132 is elastically deformed, and the first cavity 134 is reduced in volume.

As shown in fig. 7 and 9, in some embodiments, the spacing between the top pressing portion 1141 and the fixing frame is smaller than the spacing between the flange and the inner side of the door, and the first cavity 134 tends to be more circular with respect to the second cavity 1134 when in the stretched state. In the extended state, the ratio a1 of the major axis to the minor axis of the first cavity 134 is smaller than the ratio a2 of the major axis to the minor axis of the second cavity 1134, in other words, the minor axis length of the first cavity 134 is larger than the minor axis length of the second cavity 1134 in the case that the major axis lengths are equal.

The following describes the process of integrally sealing the door 111 when it is combined with the cabin 12:

as shown in fig. 7, 8 and 10, first, the lip seal 1122 is pressed by the closing of the door 111, and the portion thereof overlapped on the outer side surface (i.e., the D surface shown in fig. 8) of the door 111 is deformed by elastic force, thereby being shaped like a straight line. In the closed condition of the door 111, the portion of the lip seal 1122 that overlaps the outside surface of the door 111 will block the path between the a-side and the B-side. Next, even if moisture or foreign matter enters the passages of the a-side and the B-side, at this time, the second press seal portion 1132 fills the passage formed between the second mounting portion 1131 and the side surface of the fixing frame 1121 facing the door 111, thereby further blocking the entering moisture or foreign matter. Then, even if moisture or foreign matter passes through the passage between the second mounting portion 1131 and the side surface of the fixing frame 1221 facing the door 111, the third sealing member 13 blocks the passage between the C-face and the first mounting portion 131 to form a third protection. The second extrusion sealing portion 1132 and the first extrusion sealing portion 132 are both sealing members with a circumference formed by an elastic film, and are inflated in a natural state, and when the door 111 is closed, the first extrusion sealing portion 132 and the second extrusion sealing portion 1132 are extruded under the force of the force, so that the inner cavity formed by the elastic film is extruded, and the elastic film blocks the passageway to complete sealing.
