[0034] The present utility model provides a battery cabinet.

[0035] In the embodiments of the present utility model, as Figures 1 to 8 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 for installing a battery pack; the cabinet door 20 is rotatably installed at the first opening 12 to have a closed state of covering the first opening 12 and an open state of opening the first opening 12.

[0036] In some embodiments, the battery cabinet further includes a support mechanism 30. The support mechanism 30 is installed at the lower part of the cabinet door 20 and has a support rod 31 that moves in the up and down direction. The support rod 31 is spaced from the rotation axis of the cabinet door 20. In the open state, the support rod 31 extends downward toward the cabinet door 20 and abuts against the ground to support the cabinet door 20. Specifically, the support rod 31 is spaced from the rotation axis of the cabinet door 20 in the width direction of the cabinet door 20. In the closed state, 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 opening the door, the support rod 31 can be moved toward the ground until it abuts against 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 of the hinge 40.

[0037] The technical solution of the present utility model is to provide a support mechanism 30 at the lower part of the cabinet door 20, so that the support mechanism 30 has a support rod 31 that moves in the up and down direction 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 towards the ground to abut 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, effectively reducing the risk of deformation and damage of the hinge 40, and thus reducing the risk of failure of the cabinet door 20 due to deformation and damage of the hinge 40 in the open state.

[0038] In some embodiments, the cabinet door 20 has opposite first side portion 21 and second side portion 22, 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, both the first side portion 21 and the second side portion 22 are side portions of the cabinet door 20 perpendicular to the ground. By disposing 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 made larger, so that the cabinet door 20 can be better supported.

[0039] In some embodiments, the support mechanism 30 is disposed 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 surface of the cabinet door 20, so that the installation and use of the support mechanism 30 are convenient. Of course, in other embodiments, the support rod 31 can also be embedded in the cabinet door 20.

[0040] In some embodiments, the support mechanism 30 includes a mounting member 32 and a limit pin 33. The mounting member 32 has a first through hole 321 extending in the up and down direction and a mounting hole 322 penetrating the side wall of the first through hole 321. The support rod 31 is movably installed in the first through hole 321, and the limit pin 33 is installed in the mounting hole 322 to lock the support rod 31 in the first through hole 321. Specifically, the mounting member 32 is fixed to the cabinet door 20. When the limit pin 33 is moved into the mounting hole 322 so that the limit pin 33 is in limit cooperation with the support rod 31, the relative sliding of the support rod 31 with respect to the mounting member 32 can be restricted. Conversely, when the position of the support rod 31 needs to be adjusted, the limit pin 33 is moved out of the mounting hole 322. After the limit pin 33 is separated from the support rod 31, the support rod 31 can be adjusted to move up and down, and after the adjustment is completed, the limit pin 33 can be used to lock it. In this way, the structure of the support mechanism 30 can be simple, the cost is low, and the operation is also convenient. Of course, in other embodiments, the support rod 31 can also be driven to move up and down by a motor.

[0041] In some embodiments, the mounting hole 322 is provided with internal threads, and the limit pin 33 is provided with external threads that cooperate with the internal threads to be screwed into the mounting hole 322. In this way, the reliable limitation of the limit pin 33 can be ensured, and the risk of the limit pin 33 loosening and falling off can be reduced. Of course, in other embodiments, the limit pin 33 can also be a plug pin.

[0042] In some embodiments, the support rod 31 is provided with a plurality of limiting holes 311 which are spaced along the length direction of the support rod 31 and are all corresponding to the mounting holes 322 for the limiting pins 33 to be inserted. That is, after the limiting pins 33 are inserted into the limiting holes 311, the up-and-down movement of the support rod 31 can be restricted, thereby improving the reliability of the limit and reducing the risk of separation between the limiting pins 33 and the support rod 31.

[0043] Of course, in other embodiments, a plurality of transverse ribs may also be provided on one side of the support rod 31 corresponding to the mounting holes 322, such that the plurality of transverse ribs are spaced along the up-and-down direction, so that when the limiting pins 33 extend between two adjacent transverse ribs, the up-and-down movement of the support rod 31 can be restricted.

[0044] In some embodiments, the mounting member 32 is provided with at least two mounting holes 322 in the up-and-down direction, and a limiting pin 33 is provided at each mounting hole 322. Thus, increasing the number of the limiting pins 33 can increase the limit stability.

[0045] In some embodiments, the bottom of the support rod 31 is provided with a threaded hole, and the support mechanism 30 further includes a support foot 34 which has a screw rod 341 that is screwed into the threaded hole. Thus, when adjusting the bottom of the support rod 31 to be close to the ground, the support foot 34 can be adjusted to ensure that the support foot 34 abuts against the ground, improving the support effect.

[0046] In some embodiments, the battery cabinet further includes support rollers 70 which are provided inside the cabinet door 20 and are spaced from the rotation axis of the cabinet door 20. A support portion is provided in the first opening 12. In the closed door state, the support rollers 70 abut against the upper surface of the support portion to support the cabinet door 20. Thus, when closing the door, the cabinet door 20 can be supported by the support rollers 70, which can reduce the force on the hinge 40 of the cabinet door 20 in the closed door state and reduce the risk of deformation of the hinge 40.

[0047] Optionally, the cabinet door 20 has opposite first side portions 21 and second side portions 22. The first side portion 21 is rotatably connected to the cabinet body 10, and the support rollers 70 are arranged close to the second side portions 22. Thus, the distance between the support rollers 70 and the hinge 40 can be made larger, so as to better support the cabinet door 20.

[0048] In some embodiments, an installation portion 13 is provided inside the first opening 12, and the cabinet door 20 is provided with a connection portion 23. The connection portion 23 is spaced from the rotation axis of the cabinet door 20, that is, the connection portion 23 is spaced from the rotation axis of the cabinet door 20 in the width direction of the cabinet door 20. The battery cabinet further includes a limiting member 50. The limiting member 50 is movably installed on one of the connection portion 23 and the installation portion 13 and is detachably engaged with the other, so that when the door is in the open state, one end of the limiting member 50 is connected to the installation portion 13 and the other end is connected to the connection portion 23. When the door is in the closed state, the limiting member 50 is received inside the first opening 12 or inside the cabinet door 20.

[0049] Specifically, one end of the limiting member 50 can be movably installed on the installation portion 13, and the other end is detachably engaged with the connection portion 23, so that when the door is in the open state, one end of the limiting member 50 is connected to the installation portion 13 and the other end is connected to the connection portion 23. When the door is in the closed state, the limiting member 50 is received inside the first opening 12. Alternatively, one end of the limiting member 50 can be movably installed on the connection portion 23, and the other end is detachably engaged with the installation portion 13, so that when the door is in the open state, one end of the limiting member 50 is connected to the installation portion 13 and the other end is connected to the connection portion 23. When the door is in the closed state, the limiting member 50 is received inside the cabinet door 20.

[0050] Taking the example that one end of the limiting member 50 is movably installed on the installation portion 13 and the other end is detachably engaged with the connection portion 23, when the cabinet door 20 is in the closed state, the limiting member 50 is located inside the cabinet body 10, and at this time, the limiting member 50 is separated from the connection portion 23. After the cabinet door 20 is opened, one end of the limiting member 50 can be fixed to the installation portion 13, and the other end is connected to the connection portion 23, so that the cabinet door 20 can be prevented from rotating relative to the cabinet body 10, ensuring that the cabinet door 20 is fixed.

[0051] The technical solution of the present utility model provides a limiting member 50 on the battery cabinet, so that the limiting member 50 is movably installed on one of the connection portion 23 and the installation portion 13 and is detachably engaged with the other. In this way, when the door is closed, the limiting member 50 can be received inside the first opening 12 or inside the cabinet door 20. After the cabinet door 20 is opened, one end of the limiting member 50 can be connected to the installation portion 13 and the other end is connected to the connection portion 23, thereby limiting the cabinet door 20 and preventing the cabinet door 20 from rotating randomly in the open state, which is convenient for the staff to perform maintenance and repair work.

[0052] In some embodiments, the limiting member 50 is detachably connected to the installation portion 13 and is detachably connected to the connection portion 23. When the door is in the closed state, the limiting member 50 is received inside the first opening 12. Compared with the cabinet door 20, the size of the cabinet body 10 is larger, and there is sufficient space to receive the limiting member 50.

[0053] 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 of the two limiting rods 52 extend laterally toward the connecting rod 51. That is, one limiting rod 52 at one end of the connecting rod 51 can be hooked on the mounting portion 13, and the limiting rod 52 at the other end can be hooked on the connecting portion 23. In this way, the structure of the limiting member 50 can be simple, the size can be small, and it is convenient for storage and installation.

[0054] In some embodiments, the mounting portion 13 is provided with two first jacks 131, and the connecting portion 23 is provided with a second jack 231 extending vertically. The two limiting rods 52 extend toward the same side of the connecting rod 51. In the closed door state, each limiting rod 52 is correspondingly inserted into one first jack 131. In the open door state, one limiting rod 52 is inserted into one first jack 131, and the other limiting rod 52 is inserted into the second jack 231. In this way, when storing the limiting member 50, it can be ensured that the limiting member 50 is firmly fixed, and the connection between the limiting rod 52 and the connecting portion 23 can also be ensured to be reliable when the door is opened.

[0055] In some embodiments, the two first jacks 131 are spaced apart along the width direction of the first opening 12. That is, in the storage state, the limiting member 50 is substantially parallel to the cabinet door 20. In this way, the installation space of the limiting member 50 can be reduced, and it is also convenient for storage.

[0056] In some embodiments, the cabinet door 20 has opposite first side portions 21 and second side portions 22. The first side portion 21 is rotatably connected to the cabinet body 10, and the connecting portion 23 is disposed close to the first side portion 21. This is beneficial to reducing the size of the limiting member 50, and can also reduce the occupied space of the limiting member 50 in the open door state, avoiding obstruction to the staff.

[0057] In some embodiments, a reinforcing member 60 is provided at the position of the hinge 40 on the first side portion 21. The reinforcing member 60 extends in the vertical direction. In this way, the strength of the cabinet door 20 can be increased, and the stable installation of the hinge 40 can be ensured.

[0058] The present utility model also proposes a cabinet-type energy storage system. The cabinet-type energy storage system includes a battery pack, a battery management system, and a battery cabinet. The specific structure of the battery cabinet refers to the above embodiments. Since this cabinet-type energy storage system adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Among them, 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.
