[0044] DETAILED DESCRIPTION

[0045] ​​In the following description, numerous specific details are set forth to provide a more thorough understanding of the present application. However, it will be apparent to one of skill in the art that the present application can be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present application.

[0046] Preferred embodiments of the present application will be described herein below with reference to the drawings. It should be noted that the terms "upper", "lower", and similar terms used herein are for illustrative purposes only and are not limiting.

[0047] In this document, the ordinal numbers such as "first" and "second" cited in the present application are merely identifiers and have no other meaning, such as a specific order, etc.

[0048] For a thorough understanding of the present application, reference will be made to the following detailed description in conjunction with the accompanying drawings. It will be apparent to those skilled in the art that the present application can be practiced without one or more of the specific details set forth herein. The detailed description of the preferred embodiments of the present application is not intended to limit the scope of the present application, as claimed.

[0049] The present application provides a container door stop device. The container door stop device can be used in a container. The container includes a container body and a container door 101. The container body is configured as a substantially cuboid structure. One side of the container body is provided with a door frame 102. The door frame 102 includes a frame beam. The door frame 102 encloses a container opening. The container door 101 is pivotally connected to the door frame 102 to be able to rotate between an open position and a closed position. When the container door 101 is in the open position, the container door 101 opens the container opening. At this time, the container opening can be used to load and unload goods. When the container door 101 is in the closed position, the container door 101 can close the container opening, and at this time, the goods placed in the container body can be protected. The container can be an energy storage container for storing batteries.

[0050] Referring to Figures 1 to 4 When the container door 101 is in the closed position, the container door stop device can block the container door 101 from moving towards the open position.

[0051] Referring to Figures 1 to 4 The container door 101 has a first avoiding portion 103. The first avoiding portion 103 can be a first through hole. In this way, the strength of the container door 101 is large.

[0052] It can be understood that in an embodiment not shown, the first avoiding portion can also be a notch.

[0053] As Figure 1 and Figure 2As shown, the box door limiting device comprises a contact member 110. The contact member 110 can be a rod-like structure. The contact member 110 is located at the first avoiding part 103. One end of the contact member 110 is fixedly connected to the box door 101. The other end of the contact member 110 is suspended. In this way, the contact member 110 extends outwards to the inner side of the box door 101 (the side of the box door 101 close to the center of the box when the box door 101 is in the closed position). The contact member 110 can rotate with the box door 101.

[0054] The box door limiting device further comprises a seat body 120. The seat body 120 is located at the first avoiding part 103. There is a gap between the seat body 120 and the contact member 110. The seat body 120 comprises a body 121 and a connecting part 122. The body 121 is configured as a cylindrical structure. In this way, the strength of the body 121 is large. One end of the body 121 is connected to the frame beam. The other end of the body 121 is connected to the connecting part 122 and is suspended. In this way, the seat body 120 extends outwards to the outer side of the door frame 102 away from the center of the box. The seat body 120 is fixedly connected to the door frame.

[0055] It can be understood that in an embodiment not shown, one end of the body can also be fixedly connected to other structures of the box. For example, one end of the body is connected to the bottom plate, the side plate or other structures.

[0056] Please continue to refer to Figure 1 and Figure 2 , the box door limiting device further comprises a pivot shaft 130 and a limiting member 140. The limiting member 140 is connected to the pivot shaft 130. The connecting part 122 is provided with a pivot hole. The pivot shaft 130 is arranged in the pivot hole. In this way, the limiting member 140 is pivotally connected to the connecting part 122 through the pivot shaft 130.

[0057] The limiting member 140 can be rotated to a limiting position (the position of the limiting member 140 shown in Figure 1 ). Without the action of external force, the limiting member 140 can be kept in the limiting position. The part of the limiting member 140 in the limiting position is located to the side of the first avoiding part 103. Specifically, as shown in Figures 1 to 4 , when the box door 101 is in the closed position and the limiting member 140 is in the limiting position, the end of the projection of the limiting member 140 on the outer surface 104 of the box door 101 is located to the outer side of the first avoiding part 103 in the radial direction of the first avoiding part 103.

[0058] As shown in Figures 1 to 4As shown, the position of the seat body 120 and the first avoiding part 103 are correspondingly arranged. In this way, during the process of the box door 101 rotating towards the closed position, the seat body 120 can pass through the first avoiding part 103. The position of the contact member 110 and the position of the limiting member 140 are correspondingly arranged. In this way, during the process of the box door 101 rotating towards the closed position, the contact member 110 can contact the limiting member 140.

[0059] Please continue to refer to Figures 1 to 4 During the process of the box door 101 rotating towards the closed position, the contact member 110 contacts the limiting member 140, so that the limiting member 140 flips away from the limiting position. The limiting member 140 that flips away from the limiting position can avoid the edge of the box door 101 constituting the first avoiding part 103. In this way, the seat body 120 can pass through the first avoiding part 103 with the limiting member 140.

[0060] When the box door 101 continues to move towards the closed position to make the seat body 120 pass through the first avoiding part 103 with the limiting member 140, the limiting member 140 moves to the outside of the box door 101 away from the center of the box, and the limiting member 140 leaves the contact member 110. In this way, the contact member 110 releases the action on the limiting member 140, and the limiting member 140 can automatically flip back to the limiting position. At this time, part of the limiting member 140 in the limiting position is located on the side of the first avoiding part 103. In this way, during the process of the box door 101 rotating from the closed position towards the open position, when the box door 101 moves to the position of the limiting member 140, the limiting member 140 can block the box door 101 from continuing to rotate towards the open position. During this process, the limiting member 140 does not need to be operated by the staff.

[0061] During the process of needing to rotate the box door 101 towards the open position, the staff needs to manually flip the limiting member 140 (for example, flip 90°), so that the limiting member 140 flips away from the limiting position to avoid the edge of the box door 101 constituting the first avoiding part 103. In this way, the blocking of the limiting member 140 to the box door 101 can be released, so that the box door 101 can rotate towards the open position.

[0062] It can be understood that in an embodiment not shown, the limiting member can also be pivotally connected to the seat body through a ball hinge joint.

[0063] In the embodiment, when the container door 101 of the container with the container door limiting device rotates to the closed position, the limiting member 140 at the limiting position can block the container door 101 from rotating toward the opening position. Thus, when the door is forgotten to be locked or the door lock is damaged, the container door 101 can be prevented from rotating toward the opening position without external force, and further, the container door 101 rotating toward the opening position can be prevented from colliding with other equipment or personnel. In addition, when an explosion occurs in the container with the container door limiting device, the container door limiting device can block the container door 101, so that the blast wave of the explosion does not cause the container door 101 to fly off the container body to collide with personnel or equipment located around the container.

[0064] Preferably, there is a gap between the center of the pivotal connection of the limiting member 140 and the seat body 120 and the center of gravity of the limiting member 140, so that in a natural state, the limiting member 140 is located at the limiting position under the action of gravity. Specifically, as shown in Figure 1 and Figure 2 The limiting member 140 is configured as a substantially cuboid structure. When the limiting member 140 is located at the limiting position, the length direction of the limiting member 140 is parallel to the vertical direction. Along the width direction and the height direction of the limiting member 140, the axis of the pivotal shaft 130 (the center of the pivotal connection of the limiting member 140 and the seat body 120) is located at substantially the middle position of the limiting member 140. Along the length direction of the limiting member 140, there is a gap between the center of gravity of the limiting member 140 and the axis of the pivotal shaft 130. Thus, the limiting member 140 flipped away from the limiting position can automatically flip back to the limiting position under the action of its own gravity. In this way, the container door limiting device has a simple structure.

[0065] Further preferably, the limiting member 140 has a first side and a second side. The first side is located on one side of the center of the pivotal connection of the limiting member 140 and the seat body 120. The second side is located on the other side of the center of the pivotal connection of the limiting member 140 and the seat body 120. The first side is provided with a weight-reducing hole, so that the mass of the second side is heavier than that of the first side.

[0066] Specifically, along the length direction of the limiting member 140, the maximum distance between the pivotal shaft 130 and each end of the limiting member 140 is the same. Along the length direction of the limiting member 140, the first side is located on one side of the axis of the pivotal shaft 130, and the second side is located on the other side of the axis of the pivotal shaft 130. The limiting member 140 further has a weight-reducing hole 141. The weight-reducing hole 141 is multiple. The weight-reducing hole 141 is located on the first side. Thus, the limiting member 140 has a simple structure.

[0067] It can be understood that in an embodiment not shown, the limiting member can also be irregularly shaped. As long as there is a gap between the center of the pivotal connection of the seat body and the center of gravity of the limiting member, so that in the natural state, the limiting member is located in the limiting position under the action of gravity.

[0068] It can be understood that in an embodiment not shown, the box door limiting device can also include a reset spring. The reset spring can be a torsion spring. The reset spring can be connected to the seat body and the limiting member, for applying a force to the limiting member to keep the limiting member in the limiting position.

[0069] Further preferably, when the limiting member 140 is in the limiting position, in the vertical direction, the lower end of the limiting member 140 extends below the seat body 120, and the upper end of the limiting member 140 extends above the seat body 120. The contact member 110 is located below the seat body 120. In this way, the installation of the contact member 110 is facilitated.

[0070] It can be understood that in an embodiment not shown, in the vertical direction, the contact member is located above the seat body.

[0071] Preferably, when the box door 101 is in the closed position and the limiting member 140 is in the limiting position, the projection of the limiting member 140 on the plane where the box door 101 is located exceeds the first avoiding portion at both ends. In this way, the box door 101 in the closed position can be more effectively blocked.

[0072] As shown in Figure 5 , the length of the limiting member 140 is a, and the width is b. The inner diameter of the first avoiding portion 103 is d. a is greater than d. The distance between the end of the first avoiding portion 103 away from the contact member 110 and the contact member 110 is h. The length of the contact member 110 is L.

[0073] L is not less than a 2 +b 2 =c 2 .

[0074] In this way, the limiting member 140 can be completely moved to the outside of the box door 101, avoiding the limiting member 140 from being stuck in the first avoiding portion 103.

[0075] Please continue to refer to Figures 1 to 2 , the connecting portion 122 includes oppositely arranged first wall 123 and second wall 124. There is a gap between the first wall 123 and the second wall 124. The limiting member 140 is located in the gap. The pivot shaft 130 is provided in the first wall 123 and the second wall 124. In this way, the limiting member 140 is pivotally connected to the first wall 123 and the second wall 124. In this way, the connection between the limiting member 140 and the connecting portion 122 is firm.

[0076] As shown in Figures 1 to 4 The box door limiting device further comprises a reinforcing member 150. The reinforcing member 150 can be a plate structure. The reinforcing member 150 is provided with a second avoiding portion 151. The second avoiding portion 151 is a second through hole.

[0077] The reinforcing member 150 is used to fit and connect to the outer surface of the box door 101 (the outer surface of the box door 101 is the side of the box door 101 away from the center of the container when the box door 101 is in the closed position). The second avoiding portion 151 is in communication with the first avoiding portion 103. One end of the contact member 110 is connected to the reinforcing member 150. The contact member 110 is arranged through the first avoiding portion 103. In this way, the strength of the box door 101 at the position provided with the first avoiding portion 103 can be enhanced.

[0078] The application further provides a method for using the aforementioned box door limiting device. The method for using the box door limiting device comprises:

[0079] When the box door 101 is rotated from the open position to the closed position, the contact member 110 is in contact with the limiting member 140, so that the limiting member 140 is flipped away from the limiting position, and the seat body 120 and the limiting member 140 pass through the first avoiding portion 103;

[0080] When the seat body 120 passes through the first avoiding portion 103, the box door 101 is in the closed position, and the limiting member 140 is reset to the limiting position to block the rotation of the box door 101 towards the open position;

[0081] Before rotating the box door 101 from the closed position to the open position, the limiting member 140 is manually flipped away from the limiting position.

[0082] In this embodiment, when the box door 101 of the container using the box door limiting device is rotated to the closed position, the limiting member 140 in the limiting position can block the rotation of the box door 101 towards the open position. In this way, when the door is forgotten to be locked or the door lock is damaged, the box door 101 can be prevented from rotating towards the open position without external force, and further, the box door 101 rotating towards the open position can be prevented from colliding with other equipment or personnel. In addition, when an explosion occurs inside the container using the box door limiting device, the box door limiting device can block the box door 101 to prevent the blast wave from causing the box door 101 to fly away from the container and collide with personnel or equipment located around the container.

[0083] The application further provides a container. The container comprises:

[0084] a door frame 102 with a door opening;

[0085] The container door 101 can rotate between a closed position for closing the container opening and an open position for opening the container opening.

[0086] The aforementioned container door limiting device.

[0087] In the embodiment, the container comprises a container door limiting device. When the container door 101 rotates to the closed position, the limiting member 140 at the limiting position can block the container door 101 from rotating towards the open position. Thus, when the door is forgotten to be locked or the door lock is damaged, the container door 101 can be prevented from rotating towards the open position without external force, and further, the container door 101 rotating towards the open position can be prevented from colliding with other equipment or personnel. In addition, when an explosion occurs inside the container with the container door limiting device, the container door limiting device can block the container door 101, so that the blast wave of the explosion does not cause the container door 101 to fly off the container body and collide with personnel or equipment located around the container.

[0088] Preferably, the container door 101 has a door reinforcing beam (not shown). The contact member 110 is arranged on the door reinforcing beam. Thus, the connection strength between the contact member 110 and the container door 101 is large.

[0089] Preferably, as shown in Figure 3 and Figure 4 , the first avoiding portion 103 is located at the corner of the container door 101. Thus, the strength of the container door 101 is large. The first avoiding portion 103 is located at the lower end of the container door 101. Thus, it is convenient to operate the limiting member 140.

[0090] Preferably, the reinforcing member 150 is connected to the outer surface 104 of the container door 101. At this time, the second avoiding portion 151 and the first avoiding portion 103 are coaxially arranged. The inner diameter size of the second avoiding portion 151 is larger than the inner diameter size of the first avoiding portion 103. The inner diameter size of the second avoiding portion 151 is smaller than the length size of the limiting member 140. The part of the limiting member 140 at the limiting position is located to the side of the second avoiding portion 151. Specifically, as shown in Figure 3 and Figure 4 , when the container door 101 is at the closed position and the limiting member 140 is at the limiting position, the end of the projection of the limiting member 140 on the outer surface 104 of the container door 101 is located outside the second avoiding portion 151 in the radial direction of the second avoiding portion 151. Thus, the limiting member 140 can act on the reinforcing member 150. Thus, the container door 101 can be protected.

[0091] It can be understood that in an embodiment not shown, the first avoiding portion can also be a second through hole of the reinforcing member. At this time, the inner diameter size of the second through hole is smaller than the inner diameter size of the first through hole.

[0092] The container further comprises a door lock (not shown). The door lock is used to lock the container door at the closed position.
