[0027] In order to solve the problem that the staff cannot know whether the door lock rod is bent and deformed in the prior art, the present application provides a door body assembly for a battery cabinet and an energy storage battery cabinet.

[0028] As Figures 1 to 5 ​As shown, the battery cabinet door body assembly includes a door body 10, a top-and-bottom lock mechanism 20, a first limiting portion 30, a pressure detection device 40, and a control module. The top-and-bottom lock mechanism 20 is arranged on the door body 10, and the top-and-bottom lock mechanism 20 includes a driving mechanism and two connecting rods 21, one of which is arranged above the driving mechanism and is drivingly connected with the driving mechanism, and the other of which is arranged below the driving mechanism and is drivingly connected with the driving mechanism, so as to drive the two connecting rods 21 to move towards or away from each other through the driving mechanism, so as to realize unlocking and locking of the top-and-bottom lock mechanism 20; at least one end of the connecting rod 21 away from the driving mechanism is provided with a contact portion 50. The first limiting portion 30 is arranged on the door body 10, and is used for limiting and stopping the contact portion 50. The pressure detection device 40 is arranged between the first limiting portion 30 and the contact portion 50. The control module is electrically connected with the pressure detection device 40. If the pressure detection value of the pressure detection device 40 exceeds a preset range value, it is judged that the connecting rod 21 provided with the contact portion 50 is deformed.

[0029] The technical scheme of the embodiment is applied, in the process of the staff carrying the battery cabinet or after the carrying is completed, if the pressure detection value of the pressure detection device 40 exceeds a preset range value, it is judged that the connecting rod 21 provided with the contact portion 50 is deformed, so that the staff can detect the deformation of the connecting rod 21 in real time, if the connecting rod 21 is deformed, the staff can take corresponding strategies to open or close the door body 10, thereby solving the problem that the staff cannot know whether the door lock rod is bent and deformed in the prior art.

[0030] In the embodiment, one end of each connecting rod 21 away from the driving mechanism is provided with a contact portion 50, so as to monitor the deformation of the two connecting rods 21 in real time.

[0031] As shown in the drawings, Figure 3 Each connecting rod 21 includes oppositely arranged first and second plate bodies 211 and 212 and a third plate body 213. The first plate body 211 is connected with the second plate body 212 through the third plate body 213, the first plate body 211 and the third plate body 213 are arranged at a first included angle, and the second plate body 212 and the third plate body 213 are arranged at a second included angle; the first plate body 211 and the second plate body 212 are located on the same side of the third plate body 213. In this way, the above-mentioned design not only enhances the structural strength of the connecting rod 21 to resist external force, reduces the deformation caused by external force impact, thereby improving safety, but also facilitates assembly and maintenance of the top-and-bottom lock mechanism, and is suitable for the battery cabinet door body which is frequently opened and closed.

[0032] In this embodiment, the first plate 211 and the second plate 212 are arranged parallel to each other, with the first included angle and the second included angle both being 90°, so that the connecting rod 21 has a U-shaped structure, thereby improving the structural strength of the connecting rod 21 and preventing deformation during transportation that would affect the normal use of the battery cabinet.

[0033] Optionally, the first plate 211, the second plate 212, and the third plate 213 are integrally formed structures.

[0034] like Figure 2 As shown, there are two contact portions 50, each corresponding to one of the two connecting rods 21. Each contact portion 50 includes a mounting bracket 51 and a rolling element 52. The first side of the mounting bracket 51 is located on the end of the connecting rod 21. The rolling element 52 is rotatably mounted on the second side of the mounting bracket 51. The second side of the mounting bracket 51 is suspended, so that a mounting space 53 is formed between the rolling element 52 and the door body 10. In this way, the contact between the rolling element 52 and the first limiting part 30 can reduce the friction between them, reduce the structural wear of the contact portion 50 and the first limiting part 30, and thus extend the service life of the door assembly. At the same time, the rotation of the rolling element 52 can adapt to the small displacement of the first limiting part 30, ensuring the limiting reliability of the first limiting part 30.

[0035] In this embodiment, the mounting bracket 51 includes two fourth plates and a fifth plate arranged opposite to each other. The two fourth plates are connected by the fifth plate, and the fifth plate is perpendicular to each of the fourth plates. The rolling element 52 is rotatably mounted on the two fourth plates. The fifth plate is connected to the third plate 213 of the connecting rod 21 by fasteners.

[0036] like Figure 5 As shown, the first limiting part 30 includes a first limiting plate 31 and a second limiting plate 32. At least a portion of the first limiting plate 31 is located within the second limiting plate 32 in the mounting space 53. The second limiting plate 32 is connected to the first limiting plate 31 within the mounting space 53 and is located near the side of the connecting rod 21, with the second limiting plate 32 and the first limiting plate 31 forming a third angle. The distance between the second limiting plate 32 and the rotation axis of the rolling element 52 gradually increases along the direction from the first limiting plate 31 to the connecting rod 21. A pressure detection device 40 is provided on the first limiting plate 31 and / or the second limiting plate 32. This arrangement of the first limiting part 30 not only improves the detection accuracy of bending deformation of the connecting rod 21, allowing even minor deformation of the connecting rod 21 to be detected by the pressure detection device 40, but also prevents excessive bending deformation of the connecting rod 21, thus avoiding damage to the locking mechanism. Meanwhile, the above-mentioned settings make the placement of the pressure detection device 40 more flexible to meet different usage needs and working conditions, and also improve the processing flexibility of the staff.

[0037] In the embodiment, the pressure detection device 40 is arranged on the first limiting plate 31 and the second limiting plate 32 to monitor the stress of the connecting rod 21 in real time.

[0038] Optionally, the third included angle is greater than 180° and less than 270°.

[0039] Optionally, the pressure detection device 40 is a pressure sensing belt; and / or, the door body assembly for the battery cabinet further comprises an alarm module electrically connected with the control module, and the alarm module sends an alarm signal if the pressure detection value of the pressure detection device 40 exceeds the preset range value; and / or, the lock mechanism 20 has a self-locking module, and the self-locking module is controlled to start if the pressure detection value of the pressure detection device 40 exceeds the preset range value. In this way, the above-mentioned arrangement of the pressure sensing belt not only can realize continuous monitoring of the stress of the connecting rod 21, improve the detection accuracy, but also reduce the processing cost of the pressure detection device 40. The above-mentioned arrangement of the alarm module can immediately respond when the connecting rod 21 deforms to remind the staff to take appropriate measures. The above-mentioned arrangement of the self-locking module can prevent the battery cabinet from being opened without authorization, effectively protect the safety of internal equipment and data, reduce the safety risk, and improve the safety factor of the battery cabinet.

[0040] In the embodiment, the lock mechanism 20 has a self-locking module, and the self-locking module is controlled to start if the pressure detection value of the pressure detection device 40 exceeds the preset range value. After the self-locking module starts, the two connecting rods 21 cannot move towards each other, thereby preventing the connecting rods 21 from being forced to open and causing serious deformation of the connecting rods 21.

[0041] Optionally, the door body assembly for the battery cabinet further comprises a displacement sensor, and the displacement sensor is arranged on the door body 10 and electrically connected with the control module to detect the real-time position of the door body 10. Wherein, when the displacement sensor detects that the door body 10 is stationary, the pressure detection value of the pressure detection device 40 is controlled by the control module, and if the pressure detection value of the pressure detection device 40 exceeds the preset range value and is greater than or equal to a preset threshold value, it is judged that at least part of the connecting rod 21 provided with the contact portion 50 protrudes towards the side away from the door body 10; if the pressure detection value of the pressure detection device 40 exceeds the preset range value and is less than the preset threshold value, it is judged that at least part of the connecting rod 21 provided with the contact portion 50 protrudes towards the door body 10. In this way, the displacement sensor and the pressure detection device 40 are used in cooperation, which can more accurately judge the deformation direction of the connecting rod 21, so that the staff can compensate for the above-mentioned deformation amount and guide the staff to maintain the connecting rod 21, thereby improving the intelligent degree of the door body assembly.

[0042] As Figure 3As shown, the connecting rod 21 has a first matching part 214, and the heaven and earth lock mechanism 20 further includes a second limiting part 22, which is arranged on the door body 10 and includes a sleeve body 221 and a second matching part 222 arranged on the sleeve body 221. The sleeve body 221 is sleeved outside the connecting rod 21. One of the first matching part 214 and the second matching part 222 is a protrusion, and the other is a recess. The protrusion extends into the recess and can slide along the extension direction of the recess. In this way, during the movement of the connecting rod 21 driven by the driving mechanism, the above-mentioned arrangement of the second limiting part 22 can guide and limit the connecting rod 21, so as to ensure that the connecting rod 21 always moves in the preset direction, thereby improving the opening and closing reliability of the heaven and earth lock mechanism. At the same time, the above-mentioned arrangement makes the structure selection of the first matching part 214 and the second matching part 222 more flexible, so as to meet different use requirements and working conditions, and also improves the processing flexibility of the workers.

[0043] In the embodiment, the first matching part 214 is a recess, and the second matching part 222 is a protrusion. The protrusion extends into the recess and can slide along the extension direction of the recess.

[0044] Specifically, the recess is a waist-shaped hole, and the protrusion is a column. The column is arranged on the sleeve body 221 and extends into the waist-shaped hole. When the connecting rod 21 moves, the column slides in the waist-shaped hole to guide and limit the connecting rod 21.

[0045] Optionally, the first matching part 214 is arranged on the third plate body 213; and / or, the first matching part 214 is one, and the second limiting part 22 is one; or, the first matching part 214 is multiple, the multiple first matching parts 214 are arranged at intervals along the extension direction of the connecting rod 21, and the second limiting part 22 is multiple, and the multiple second limiting parts 22 are arranged in one-to-one correspondence with the multiple first matching parts 214. In this way, by arranging multiple first matching parts 214 at different positions of the connecting rod 21 and arranging multiple second limiting parts 22 in one-to-one correspondence with the multiple first matching parts 214, the guiding reliability and limiting stability of the second limiting part 22 to the connecting rod 21 are improved, and the opening and closing reliability of the heaven and earth lock mechanism is further improved.

[0046] In the embodiment, by arranging the first matching part 214 on the third plate body 213, the cooperation between the second limiting part 22 and the first matching part 214 does not affect the normal opening and closing of the door body 10.

[0047] As Figure 1 and Figure 3As shown, the door body assembly for battery cabinet further comprises a lock catch 60 arranged on the first plate body 211 or the second plate body 212, and the lock catch 60 comprises a connecting plate 61 and a hook-shaped portion 62. The connecting plate 61 is connected with the first plate body 211 or the second plate body 212, and the hook-shaped portion 62 is arranged on the connecting plate 61 and protrudes from the third plate body 213. In this way, the design of the lock catch 60 not only can realize the locking function of the overhead lock mechanism, but also can enhance the connection strength between the connecting rod 21 and the door body 10, so as to effectively prevent illegal intrusion, protect the safety of the equipment inside the battery cabinet, and reduce the security risk. At the same time, the above arrangement makes the structure of the lock catch 60 simpler, easier to process and realize, and reduces the processing cost and difficulty of the lock catch 60.

[0048] In the embodiment, the hook-shaped portion 62 is arranged upward.

[0049] As shown, Figure 5 As shown, the first limiting portion 30 further comprises a transition connecting plate 33, the transition connecting plate 33 is connected with the side of the first limiting plate 31 away from the connecting rod 21, and the transition connecting plate 33 and the first limiting plate 31 are arranged at a fourth included angle and are arranged opposite to the rolling body 52. The first limiting portion 30 is connected with the door body 10 through the transition connecting plate 33. In this way, the above arrangement makes the disassembly of the first limiting portion 30 easier and simpler, and reduces the disassembly difficulty.

[0050] Optionally, the fourth included angle is 90°.

[0051] The application further provides a battery cabinet (not shown) comprising the above-mentioned door body assembly for battery cabinet.
