[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0046] In conventional technologies, a common structure involves the door panel being embedded within the door frame, sealed with a sealing strip for dust and water protection, and the locking rod being external. In this structure, the locking rod is located on the outside of the container, exposed to the outdoor environment, making it prone to corrosion. Furthermore, the appearance of the locking rod clashes with the overall style and color of the container, affecting its aesthetics. Another structure places the door panel outside the container door frame, sealed with a sealing strip on the frame, with the locking rod located on the inner side of the door panel. While this structure reduces the exposure of the locking rod to some extent, it is still susceptible to corrosion, and the door panel and locking rod are weaker and more prone to deformation.

[0047] Therefore, this application provides a door structure and an energy storage container. By embedding the locking rod inside the door panel or setting it on the inner side of the door panel, that is, setting it inside the container, the locking rod is prevented from being directly exposed to the outdoor environment, reducing the occurrence of rust, thereby extending the service life of the container and ensuring its aesthetics.

[0048] Figure 1 This is a first-view structural diagram of the lock rod provided in Embodiment 1 of this application, which is located on the inner side of the door panel. Figure 2 This is a schematic diagram of the second view of the structure provided in Embodiment 1 of this application, showing the lock rod placed on the inner side of the door panel. Figure 3 This is a third-view structural diagram of the lock rod provided in Embodiment 1 of this application, with the lock rod positioned on the inner side of the door panel.

[0049] Please see Figure 1 , Figure 2 and Figure 3This application provides a door structure for use in energy storage containers. The door structure includes a door frame 1, a door panel 2, and a door lock assembly 3. The door lock assembly 3 is used to lock and unlock the door frame 1 and the door panel 2. The door lock assembly 3 includes a lock seat 31, a lock cylinder 32, a lock rod 33, a handle 34, a handle seat 35, and a small door 36. The lock seat 31 is installed on the inner side of the door frame 1. The lock cylinder 32 is connected to the end of the lock rod 33, which is embedded in the door panel 2. The handle 34 is located in the handle seat 35 and connected to the lock rod 33. The handle seat 35 protrudes from the inner side of the door panel 2. The small door 36 is rotatably connected to the handle seat 35 to close the opening 37 of the handle seat 35. Under external force, the handle 34 drives the lock rod 33 to move, thereby locking or unlocking the door frame 1 and the door panel 2.

[0050] Specifically, the energy storage container has an inner side and an outer side that are opposite to each other. The inner side of the door frame 1 and the inner side of the door panel 2 are both the inner side of the energy storage container.

[0051] The locking rod 33 is installed on the inner side of the door panel 2, which solves the problems of easy corrosion of the locking rod, affecting the appearance, and insufficient strength of the door panel and locking rod in the prior art. In addition, this design ensures that even if the door panel 2 is damaged to a certain extent, the door lock assembly 3 can still remain intact and is not easy to be pried open or damaged.

[0052] Furthermore, the design connecting the handle 34 to the locking rod 33 allows users to control the entire lock's opening and closing with simple rotation or push operations, greatly improving ease of use. Under external force, such as rotating the handle 34, the handle 34 drives the locking rod 33 to move horizontally (perpendicular to the axial direction of the locking rod 33), thereby connecting or disconnecting the lock head 32 from the lock seat 31. This process quickly locks and unlocks the door panel 2, facilitating user operation.

[0053] Figure 4 This is a schematic diagram of the connection between the lock rod and the lock seat provided in Embodiment 1 of this application. Figure 5 for Figure 4 Enlarged view of part A in the middle.

[0054] In some embodiments, please refer to Figure 4 and Figure 5The lock base 31 includes a first fixing part 311 and a first engaging part 312 connected together. The first engaging part 312 passes through the doorway 11, and the orthographic projection of the first fixing part 311 on the door frame 1 is located outside the doorway 11. The lock cylinder 32 includes a rotating sleeve 321 and a second engaging part 322. The rotating sleeve 321 is fixedly connected to the lock rod 33, and the second engaging part 322 is connected to one end of the rotating sleeve 321. In the locked state of the door frame 1 and the door panel 2, the second engaging part 322 and the first engaging part 312 are engaged with each other; in the unlocked state of the door frame 1 and the door panel 2, the second engaging part 322 and the first engaging part 312 are disengaged from each other.

[0055] Understandably, please refer to Figure 2 and Figure 4 Since the projection of the first fixing part 311 is located outside the doorway 11, it ensures that when the door frame 1 and door panel 2 are locked, the first fixing part 311 of the lock seat 31 will not interfere with the normal opening and closing of the door. This design reduces the possibility of misoperation. When the door frame 1 and door panel 2 are locked, the first latching part 312 and the second latching part 322 engage with each other, forming a stable connection. This makes the connection between the door panel 2 and the door frame 1 more secure and less susceptible to damage from external forces, thus improving security. When the door frame 1 and door panel 2 are unlocked, the second latching part 322 moves away from the first latching part 312, allowing the door panel 2 to move freely. This makes the unlocking process simple and quick, allowing users to easily open the door.

[0056] In some embodiments, please refer to Figure 3 The handle base 35 protrudes from the inner side of the door panel 2. The door panel 2 has an opening 37 communicating with the handle base 35. A small door 36 is rotatably connected to the door panel 2 to close the opening 37. The handle 34 is disposed within the handle base 35. Because the handle 34 is disposed within the handle base 35 and the opening 37 is closed by rotating the small door 36, the handle 34 is prevented from being directly exposed to the outdoor environment, reducing rust and extending the service life of the container. Simultaneously, the handle 34 can be concealed, improving the aesthetics of the door structure.

[0057] In addition, when enhanced security is required, latches can be installed on the small door 36 and the door panel 2. This makes it more difficult for outsiders to directly touch or damage the door lock when the small door 36 is turned to close the opening 37.

[0058] Please see Figure 3 The handle base 35 has a through hole 38 extending vertically, and the locking rod 33 passes through the through hole 38. Since the locking rod 33 is directly connected to the handle 34 through the through hole 38, additional mechanical connecting parts are eliminated, simplifying the internal structure of the entire door lock assembly 3. This design not only reduces the number of parts but also lowers potential failure points, improving the overall system reliability.

[0059] In some embodiments, the door structure further includes multiple locking rod brackets 4, each locking rod 33 bracket being fixed to the inner side of the door panel 2. The locking rod 33 bracket supports the locking rod 33, and the locking rod 33 is rotatably connected to the locking rod 33 bracket. The locking rod 33 bracket provides additional support, making the locking rod 33 more stable inside the door panel 2. That is, the locking rod 33 bracket supports the locking rod 33 to reduce potential shaking or deformation of the locking rod 33 during use, thereby improving the overall stability of the locking system.

[0060] In some embodiments, the door structure further includes two limiting sleeves 5, which are sleeved on the locking rod 33 and located on both sides of the locking rod 33 bracket in the vertical direction. The limiting sleeves 5 provide physical restraint on both sides of the locking rod 33 bracket, preventing unnecessary movement of the locking rod 33 in the vertical direction, ensuring that the locking rod 33 remains in the correct position during operation, and improving the reliability of locking and unlocking.

[0061] In some embodiments, please refer to Figure 2 The height of the door panel 2 is equal to the height of the locking rod 33. Since the height of the door panel 2 and the height of the locking rod 33 are the same, this means that there is no extra space wasted in the vertical direction of the door. This helps to increase the internal space of the energy storage container and is more aesthetically pleasing than traditional energy storage container door locks.

[0062] In this embodiment, please refer to Figure 2 The locking rod 33 is located on the inner side of the door panel 2. The locking rod 33 features an external horizontal rotating structure and a concealed handle 34 design, solving the problems of easy corrosion of the locking rod 33, its unsightly appearance, and insufficient strength of the door body and locking rod 33 in existing technologies. Simultaneously, the door structure is suitable for energy storage containers, improving the sealing and aesthetics of the energy storage container.

[0063] Figure 6 This is a structural schematic diagram of the lock rod hidden inside the door panel from a first-view perspective, provided in Embodiment 2 of this application. Figure 7 This is a structural schematic diagram from a second perspective of the lock rod hidden inside the door panel provided in Embodiment 2 of this application.

[0064] Please see Figure 6 and Figure 7The door structure provided in this embodiment is applied to an energy storage container. The door structure includes a door frame 1, a door panel 2, and a door lock assembly 3. The door lock assembly 3 is used to lock and unlock the door frame 1 and the door panel 2. The door lock assembly 3 includes a lock seat 31, a lock cylinder 32, a lock rod 33, a handle 34, a handle seat 35, and a small door 36. The lock seat 31 is installed on the inner side of the door frame 1. The lock cylinder 32 is connected to the end of the lock rod 33. The lock rod 33 is embedded in the door panel 2. The handle 34 is located in the handle seat 35 and connected to the lock rod 33. The handle seat 35 protrudes from the inner side of the door panel 2. The small door 36 is rotatably connected to the handle seat 35 to close the opening 37 of the handle seat 35. Under the action of external force, the handle 34 drives the lock rod 33 to move, thereby locking or unlocking the door frame 1 and the door panel 2.

[0065] Figure 8 This is a schematic diagram of the structure of two connecting rods connected to a rotary cam as provided in Embodiment 2 of this application. Figure 9 for Figure 8 Schematic diagram of the structure of part B in the middle.

[0066] In some embodiments, please refer to Figure 8 and Figure 9 The door structure also includes a rotating cam 6, which is located within the handle seat 35 and connected to the handle 34. The locking rod 33 has two connecting rods 331 that cooperate with the rotating cam 6. When the rotating cam 6 rotates, the connecting rods 331 move vertically up and down to lock or unlock the door frame 1 and the door panel 2. It is understood that a rack is provided at the root of the connecting rod 331 connected to the rotating cam 6, meshing with the rotating cam 6, so that the rotating cam 6 drives the rack to move when it rotates. Furthermore, a limiting strip can be provided on the rotating cam 6 to limit its rotation angle, thereby restricting the vertical movement range of the two connecting rods 331.

[0067] With the door frame 1 and door panel 2 locked, the handle 34 is lifted upwards so that the rotating cam 6 rotates counterclockwise. The rotating cam 6 drives the two connecting rods 331 to move in opposite directions in the vertical direction, so that the lock head 32 connected to the connecting rod 331 is engaged in the lock seat 31, thereby locking the door frame 1 and door panel 2.

[0068] With the door frame 1 and door panel 2 unlocked, the handle 34 is pressed down to make the rotating cam 6 rotate clockwise. The rotating cam 6 drives the two connecting rods 331 to move towards each other in the vertical direction, thereby causing the lock head 32 connected to the connecting rods 331 to disengage from the lock seat 31, thus unlocking the door frame 1 and door panel 2.

[0069] In some embodiments, the locking rod 33 is embedded in the door panel 2. Under the action of external force, the handle 34 drives the locking rod 33 to move in the vertical direction so that the lock head 32 is fixed in the lock seat 31; wherein, the vertical direction is the axial direction of the locking rod 33.

[0070] Specifically, the locking rod 33 is embedded within the door panel 2, meaning it is hidden within the door panel 2. Since the movement of the locking rod 33 is vertical, even if the door panel 2 is deformed or damaged by external forces, the locking rod 33 can still maintain its axial alignment, thus maintaining the normal connection between the lock head 32 and the lock seat 31. Furthermore, when unlocking, the user simply needs to rotate the handle 34 vertically to trigger the two connecting rods 331 to move up and down vertically, quickly locking and unlocking the door panel 2. This operation is simple and quick, requiring no complicated steps, and improving the convenience of daily use.

[0071] In some embodiments, the door structure further includes a linkage bracket 7, each linkage bracket 7 being fixed to the inner side of the door panel 2. The locking rod 33 bracket supports the connecting rod 331, and the connecting rod 331 is slidably connected to the linkage bracket 7. The linkage bracket 7 provides a stable support structure for the connecting rod 331, ensuring that the connecting rod 331 remains on the correct track during operation, thereby reducing the shaking and offset of the connecting rod 331 and improving the reliability of locking and unlocking.

[0072] In some embodiments, when the door frame 1 and door panel 2 are unlocked, the orthographic projections of the two connecting rods 331 in the reference plane are located within the orthographic projections of the door panel 2 in the reference plane. This means that the connecting rods 331 will not exceed the boundary of the door panel 2 in the unlocked state, ensuring that the door can be fully opened in the unlocked state without being restricted by the connecting rods 331. At the same time, this improves the aesthetics of the energy storage container.

[0073] Figure 10 This is a first-view structural diagram of the lock rod located on the inner side of the door panel, as provided in Embodiment 3 of this application. Figure 11 This is a schematic diagram of the second view of the structure provided in Embodiment 3 of this application, showing the lock rod placed on the inner side of the door panel.

[0074] Please see Figure 10 and Figure 11 The locking rod 33 is located on the inner side of the door panel 2. Under the action of external force, the handle 34 drives the locking rod 33 to move in the vertical direction so that the lock head 32 is fixed in the lock seat 31.

[0075] Specifically, please refer to Figure 10 and Figure 11The locking rod 33 is located on the inner side of the door panel 2, meaning it is externally mounted on the door panel 2 and situated inside the energy storage container. Since the movement of the locking rod 33 is vertical, even if the door panel 2 is deformed or damaged by external forces, the locking rod 33 can still maintain its axial alignment, thus preserving the normal connection between the lock head 32 and the lock seat 31. Furthermore, when unlocking, the user only needs to simply rotate the handle 34 vertically to trigger the axial movement of the locking rod 33, quickly locking and unlocking the door panel 2. This operation is simple and quick, requiring no complicated steps, and improving the convenience of daily use.

[0076] Therefore, this embodiment solves the problems of easy corrosion of the locking rod 33, affecting aesthetics, and insufficient strength of the door body and locking rod 33 in the prior art by setting the locking rod 33 on the inner side of the door panel 2, and providing a vertically retractable locking rod 33 or lock head 32, as well as a concealed handle 34. At the same time, the door structure is suitable for energy storage containers, improving the sealing and aesthetics of the energy storage containers.
