[0033] The utility model provides a battery cabinet.

[0034] In the embodiment of the present utility model, Figures 1 to 8 As shown, the battery cabinet includes a cabinet body 10 and a cabinet door 20. The cabinet body 10 is provided with an installation cavity 11 and a first opening 12 located on one side. The first opening 12 is communicated with the installation cavity 11, and the installation cavity 11 is used to install a battery pack; the cabinet door 20 is rotatably installed at the first opening 12 to have a closed state covering the first opening 12 and an open state opening the first opening 12.

[0035] In some embodiments, the battery cabinet further includes a support mechanism 30, which is mounted on the lower portion of the cabinet door 20 and includes a support rod 31 that moves in an up-down direction. The support rod 31 is spaced apart from the rotation axis of the cabinet door 20. When the door is open, the support rod 31 extends downward from the cabinet door 20 and abuts the ground to support the cabinet door 20. Specifically, the support rod 31 is spaced apart from the rotation axis of the cabinet door 20 in the width direction of the cabinet door 20. When the door is closed, the lower end of the support rod 31 does not extend beyond the lower edge of the cabinet door 20 to avoid affecting the normal closing of the cabinet door 20. After the door is opened, the support rod 31 can be moved upward until it abuts the ground. At this time, the support rod 31 is fixed to the cabinet door 20, so that the cabinet door 20 can be supported by the support rod 31, thereby reducing the force on the hinge 40 between the cabinet door 20 and the cabinet body 10 and reducing the risk of deformation and damage to the hinge 40.

[0036] The technical solution of the present invention is to set a support mechanism 30 at the lower position of the cabinet door 20, so that the support mechanism 30 has a support rod 31 that moves in the up and down directions and is spaced from the rotation axis of the cabinet door 20. In this way, when the cabinet door 20 is opened to the open state, the support rod 31 can be moved in the direction and abutted against the ground, so that the cabinet door 20 can be supported by the support mechanism 30, reducing the force on the hinge 40 of the cabinet door 20, and effectively reducing the risk of deformation and damage of the hinge 40, thereby reducing the risk of malfunction of the cabinet door 20 due to deformation and damage of the hinge 40 in the open state.

[0037] In some embodiments, the cabinet door 20 has a first side portion 21 and a second side portion 22 that are opposite to each other. The first side portion 21 is rotatably connected to the cabinet body 10, and the support mechanism 30 is disposed near the second side portion 22. Specifically, the first side portion 21 and the second side portion 22 are both side portions of the cabinet door 20 that are perpendicular to the ground. By arranging the support mechanism 30 closer to the second side portion 22 than the first side portion 21, the distance between the support mechanism 30 and the hinge 40 can be increased, thereby better supporting the cabinet door 20.

[0038] In some embodiments, the support mechanism 30 is provided on the side of the cabinet door 20 facing the installation cavity 11, that is, the support mechanism 30 is installed on the inner side of the cabinet door 20, which facilitates the installation and use of the support mechanism 30. Of course, in other embodiments, the support rod 31 can also be embedded in the cabinet door 20.

[0039] In some embodiments, the support mechanism 30 includes a mounting member 32 and a stop pin 33. The mounting member 32 has a first through hole 321 extending vertically and a mounting hole 322 extending through the side wall of the first through hole 321. The support rod 31 is movably mounted in the first through hole 321, and the stop pin 33 is mounted in the mounting hole 322 to lock the support rod 31 within the first through hole 321. Specifically, the mounting member 32 is fixed to the cabinet door 20. When the stop pin 33 is moved toward the mounting hole 322 so that the stop pin 33 and the support rod 31 are locked, the support rod 31 is restricted from sliding relative to the mounting member 32. Conversely, when the position of the support rod 31 needs to be adjusted, the stop pin 33 is moved out of the mounting hole 322. After the stop pin 33 is away from the support rod 31, the support rod 31 can be adjusted to move up and down. After the adjustment is completed, the stop pin 33 is used to lock the support rod 31. This makes the structure of the support mechanism 30 simple, low-cost, and easy to operate. Of course, in other embodiments, the support rod 31 may also be driven by a motor to move up and down.

[0040] In some embodiments, the mounting hole 322 is provided with an internal thread, and the stop pin 33 is provided with an external thread that matches the internal thread, so as to be screwed into the mounting hole 322. This ensures that the stop pin 33 is securely positioned and reduces the risk of the stop pin 33 loosening and falling. Of course, in other embodiments, the stop pin 33 can also be a latch.

[0041] In some embodiments, the support rod 31 is provided with a plurality of limiting holes 311, which are spaced apart along the length of the support rod 31 and correspond to the mounting holes 322 for insertion of the limiting pin 33. In other words, once the limiting pin 33 is inserted into the limiting hole 311, the support rod 31 is restricted from moving up and down, thereby improving the reliability of the limiting position and reducing the risk of the limiting pin 33 separating from the support rod 31.

[0042] Of course, in other embodiments, multiple transverse ribs can also be set on one side of the support rod 31 corresponding to the mounting hole 322, so that the multiple transverse ribs are spaced apart in the up and down directions, so that when the limit pin 33 extends between two adjacent transverse ribs, the support rod 31 can be restricted from moving up and down.

[0043] In some embodiments, the mounting member 32 is provided with at least two mounting holes 322 in the up and down directions, and each mounting hole 322 is provided with a limiting pin 33. Increasing the number of limiting pins 33 can increase the limiting stability.

[0044] In some embodiments, the bottom of the support rod 31 is provided with a screw hole, and the support mechanism 30 further includes a support foot 34 having a screw 341 that is screwed into the screw hole. In this way, when adjusting the bottom of the support rod 31 closer to the ground, the support foot 34 can be adjusted to ensure that the support foot 34 is in contact with the ground, thereby improving the support effect.

[0045] In some embodiments, the battery cabinet further includes a support roller 70, which is disposed inside the cabinet door 20 and spaced apart from the rotation axis of the cabinet door 20. A support portion is disposed within the first opening 12. When the cabinet door is closed, the support roller 70 abuts against the upper surface of the support portion to support the cabinet door 20. This allows the support roller 70 to support the cabinet door 20 when closed, thereby reducing the force on the hinge 40 of the cabinet door 20 when closed and lowering the risk of deformation of the hinge 40.

[0046] Optionally, the cabinet door 20 has a first side portion 21 and a second side portion 22 relative to each other, the first side portion 21 is rotatably connected to the cabinet body 10, and the support roller 70 is arranged close to the second side portion 22, so that the distance between the support roller 70 and the hinge 40 can be larger, thereby better supporting the cabinet door 20.

[0047] In some embodiments, a mounting portion 13 is provided inside the first opening 12, and a connecting portion 23 is provided on the cabinet door 20. The connecting portion 23 is spaced apart from the rotation axis of the cabinet door 20, that is, the connecting portion 23 and the rotation axis of the cabinet door 20 are spaced apart in the width direction of the cabinet door 20. The battery cabinet further includes a stopper 50, which is movably mounted on one of the connecting portion 23 and the mounting portion 13 and detachably engages with the other. When the door is open, one end of the stopper 50 is connected to the mounting portion 13, and the other end is connected to the connecting portion 23. When the door is closed, the stopper 50 is stored inside the first opening 12 or inside the cabinet door 20.

[0048] Specifically, one end of the limiting member 50 can be movably mounted on the mounting portion 13, and the other end can be detachably engaged with the connecting portion 23, so that when the door is open, one end of the limiting member 50 is connected to the mounting portion 13, and the other end is connected to the connecting portion 23, and when the door is closed, the limiting member 50 is stored inside the first opening 12. Alternatively, one end of the limiting member 50 can be movably mounted on the connecting portion 23, and the other end can be detachably engaged with the mounting portion 13, so that when the door is open, one end of the limiting member 50 is connected to the mounting portion 13, and the other end is connected to the connecting portion 23, and when the door is closed, the limiting member 50 is stored inside the cabinet door 20.

[0049] Taking the example of a position-limiting member 50 in which one end is movably mounted on the mounting portion 13 and the other end is detachably engaged with the connecting portion 23, when the cabinet door 20 is closed, the position-limiting member 50 is located within the cabinet body 10, and the position-limiting member 50 is separated from the connecting portion 23. After the cabinet door 20 is opened, one end of the position-limiting member 50 can be fixed to the mounting portion 13 and the other end can be connected to the connecting portion 23, thereby preventing the cabinet door 20 from rotating relative to the cabinet body 10 and ensuring that the cabinet door 20 is fixed.

[0050] The present invention provides a position-limiting member 50 on the battery cabinet, allowing it to be movably mounted on one of the connecting portion 23 and the mounting portion 13 and detachably engaged with the other. This allows the position-limiting member 50 to be retracted into the first opening 12 or into the cabinet door 20 when the door is closed. When the cabinet door 20 is opened, one end of the position-limiting member 50 can be connected to the mounting portion 13 and the other end to the connecting portion 23, thereby limiting the position of the cabinet door 20 and preventing it from rotating freely when open. This facilitates maintenance and inspection work.

[0051] In some embodiments, the stopper 50 is detachably connected to the mounting portion 13 and the connecting portion 23. When the door is closed, the stopper 50 is stored inside the first opening 12. Compared to the cabinet door 20, the cabinet body 10 is larger and has ample space to store the stopper 50.

[0052] In some embodiments, the limiting member 50 includes two limiting rods 52 and a connecting rod 51 connected between the two limiting rods 52. Both limiting rods 52 extend laterally from the connecting rod 51. That is, the limiting rod 52 at one end of the connecting rod 51 can be hooked on the mounting portion 13, while the limiting rod 52 at the other end of the connecting rod 51 can be hooked on the connecting portion 23. This makes the limiting member 50 simple in structure and small in size, making it easy to store, install, and use.

[0053] In some embodiments, the mounting portion 13 is provided with two first insertion holes 131, the connecting portion 23 is provided with a second insertion hole 231 extending vertically, and the two limiting rods 52 extend toward the same side of the connecting rod 51. When the door is closed, each limiting rod 52 is inserted into a corresponding first insertion hole 131. When the door is open, one limiting rod 52 is inserted into one of the first insertion holes 131, and the other limiting rod 52 is inserted into the second insertion hole 231. This ensures that the limiting member 50 is securely fixed when it is stored, and also ensures that the limiting rod 52 is securely connected to the connecting portion 23 when the door is open.

[0054] In some embodiments, the two first insertion holes 131 are spaced apart along the width direction of the first opening 12. That is, in the storage state, the limiter 50 is substantially parallel to the cabinet door 20, which can reduce the installation space of the limiter 50 and facilitate storage.

[0055] In some embodiments, the cabinet door 20 has a first side portion 21 and a second side portion 22 that are opposite to each other. The first side portion 21 is rotatably connected to the cabinet body 10, and the connecting portion 23 is disposed near the first side portion 21. This helps reduce the size of the stopper 50 and the space occupied by the stopper 50 when the door is open, thereby preventing the stopper from obstructing the operator.

[0056] In some embodiments, a reinforcement member 60 is provided at the position where the hinge 40 is provided on the first side portion 21 , and the reinforcement member 60 extends in the up-down direction, thereby increasing the strength of the cabinet door 20 and ensuring that the hinge 40 is stably installed.

[0057] The present invention also provides a cabinet-type energy storage system, which includes a battery pack, a battery management system, and a battery cabinet. The specific structure of the battery cabinet is similar to the above-mentioned embodiments. Since this cabinet-type energy storage system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and will not be described in detail here. The battery pack is disposed in the installation cavity 11 of the battery cabinet, and the battery management system is electrically connected to the battery pack. Optionally, there are multiple battery packs, and each of the multiple battery packs is installed in the installation cavity 11.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
