[0026] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0027] The energy storage cabinet of the present invention comprises a cabinet door 10, a housing (not shown) and a limiting mechanism arranged between the housing and the cabinet door. The limiting mechanism of the present invention comprises a first fixing member 20, a second fixing member 30, a connecting rod mechanism 40, a curved rod 50, a locking member 60, a torsion spring 80 and a plurality of rotating shafts 70.

[0028] The first fixing member 20 is constructed as a convex body, and is provided with a plurality of positioning holes and a first fixing member through hole. The first fixing member 20 can be positioned on the shell of the energy storage cabinet through the positioning holes using fasteners such as screws, and the first fixing member 20 can be further fixed to the inside of the shell.

[0029] The bent rod 50 is constructed as a curved rod structure, and is preferably made of a high-strength and light-weight material such as stainless steel to ensure that it has sufficient strength. The bent rod 50 is provided with a first bent rod through hole 501 and a second bent rod through hole 502. The first bent rod through hole 501 is provided at the first end of the bent rod 50; the second bent rod through hole 502 is provided at a position close to the second end. A limiting protrusion 503 and a groove 504 are provided at the second end of the bent rod 50.

[0030] The connecting rod mechanism 40 includes a first connecting rod 401 and a second connecting rod 402, which are arranged in parallel in the vertical direction, and the structures of the first connecting rod and the second connecting rod are basically the same. Each of the first connecting rod 401 and the second connecting rod 402 is provided with three through holes at intervals, namely, a first connecting rod through hole 4011, a second connecting rod through hole 4012 and a third connecting rod through hole 4013. The first connecting rod through hole 4011 is arranged at the first end of the first connecting rod, the third connecting rod through hole 4013 is arranged at the second end, and the second connecting rod through hole 4012 is located at the middle position of the connecting rod. The difference between the first connecting rod 401 and the second connecting rod 402 is that a limiting portion 4014 is also arranged on the first connecting rod 401, and the limiting portion 4014 is configured as a protrusion protruding from the main body of the first connecting rod 401 toward the second connecting rod 402.

[0031] The locking member 60 is constructed as follows Figure 6 The tongue-shaped portion shown includes a locking protrusion 603 arranged at the first end and a recessed portion 604 adjacent to the locking protrusion. The second end of the locking component 60 is provided with a locking component through hole 601, and a handle portion 602 arranged between the first end and the second end. The handle portion 602 is constructed as a protrusion protruding outward from the main body of the locking component, so that when the user needs to operate the locking component, force can be applied to the locking component 60 by holding the handle portion 602.

[0032] The second fixing member 30 is constructed as a triangular hollow shape parallel to each other, with a through hole and a positioning hole extending vertically. The second fixing member 30 is constructed so as to be fixed to the cabinet door 10 of the energy storage cabinet by passing screws or other components through the positioning hole.

[0033] The shaft mechanism 70 is constructed as follows Figure 7 The shown shape includes a rotating shaft 703 and an upper end 701 and a lower end 702, wherein the upper end 701 and the lower end 702 are constructed to be detachably connected to the rotating shaft 703, preferably, the upper end 701 and the lower end 702 are constructed as bolts; the upper and lower ends of the rotating shaft 703 are respectively provided with threaded structures, so that the upper end 701, the lower end 702 and the rotating shaft 703 can be fastened and connected with the rotating shaft 703 by bolts and threads to form a rotating shaft connection.

[0034] The following will introduce the assembly method and working principle of the cabinet door limit mechanism of the utility model in detail with reference to the accompanying drawings. Figure 1-8 As shown, the cabinet door limiting mechanism of the present invention can be assembled according to the following steps and methods.

[0035] The first fixing member 20 and the second fixing member 30 are fixed to the box body (not shown) and the cabinet door 10 of the energy storage cabinet by screws, respectively. The first through hole 501 of the bent rod 50 is aligned with the first through hole 201 of the first fixing member, and then the first rotating shaft 700 passes through the first through hole 501 and the first through hole 201 of the first fixing member, and then the upper end 701 and the lower end 702 are respectively fixed to the two ends of the rotating shaft 703 to fix the first end of the bent rod 50 to the first fixing member 20 through the first rotating shaft 700. Then the second through hole 502 of the bent rod and the through hole 4011 of the first connecting rod on the bent rod 50 are aligned, and then the second rotating shaft 7001 passes through the second through hole 502 of the bent rod and the through hole 4011 of the first connecting rod, and then the upper end 701 and the lower end 702 of the rotating shaft are respectively fixed to the two ends of the second rotating shaft. The locking through hole 601 of the locking component is aligned with the second connecting rod through hole 401 of the first connecting rod 401 and the second connecting rod 402, and then the torsion spring 80 is set in the space between the first connecting rod 401 and the second connecting rod 402 and aligned with the second connecting rod 401, and the rotating shaft rotates the first connecting rod 401, the second connecting rod 402, and the torsion spring 80 at the same time to form a rotating shaft connection. The third connecting rod through hole 4012 of the first connecting rod 401 and the second connecting rod 402 is aligned with the through hole of the second fixing member 30, and then connected through the fourth rotating shaft 7003. Through the above steps, the cabinet door limiting mechanism of the utility model can be installed.

[0036] The following is combined with Figure 10-12 , describes in detail how the cabinet door limiting mechanism of the utility model realizes the limiting function of the cabinet door of the energy storage cabinet.

[0037] When the energy storage cabinet is operating normally, the cabinet door 10 is closed. At this time, the cabinet door limit mechanism is in the following state: Fig.10 The locking member 60 is in the folded state shown. Under the elastic force of the torsion spring, the locking protrusion 603 of the locking member is located outside the connecting rod mechanism 40, the bent rod 50 is in the folded state, the limiting protrusion 503 of the bent rod 50 is also located outside the connecting rod mechanism, the bent rod 50 and the connecting rod mechanism 40 are connected by the second rotating shaft 7001, and the two can move freely without being restricted by each other. At this time, the limiting mechanism has no limiting function.

[0038] When the user needs to repair the energy storage cabinet or replace the battery, the user will apply force to the cabinet door 10, so that the second fixing member 30 moves with the cabinet door 10. The second fixing member 30 moves while driving the connecting rod mechanism 40 to move together. When the cabinet door 10 is opened to a certain angle, the second end of the curved rod 50 forms a straight line with the connecting rod mechanism 40. The second end of the curved rod 50 is limited by the limit part 4014 on the connecting rod mechanism and cannot be opened further. At this time, the door panel 10 is opened to the maximum angle, and the cabinet door limit mechanism is in a free state. If there is a strong wind blowing the door, it may cause the door panel 10 to return to the state as shown in the figure. Fig.10 Shown in folded state.

[0039] At this time, the user needs to manually move the locking component 60 so that the locking protrusion 603 of the locking component enters the groove 504 at the end of the curved rod 50, and the limiting protrusion 503 on the curved rod enters the recessed portion 604 of the locking component. The locking component 60 and the curved rod 50 form a snap-fit ​​structure and self-lock with each other to maintain a locked state. In this state, even if there is a strong wind blowing the cabinet door, due to the interlocking structure formed by the locking component 60 and the curved rod 50, the cabinet door cannot be closed, but remains in an open state. Therefore, it can prevent injuries to operators due to abnormal closing of the cabinet door. At this time, the cabinet door limiting mechanism is in a state as follows: Figure 2 Lock status shown.

[0040] When the cabinet door 10 needs to be closed, the operator needs to hold the handle 602 on the locking component 60 and rotate the locking component 60 so that the locking protrusion 603 leaves the groove 504, and the limiting protrusion 503 also leaves the recessed portion 604, and the locking component 60 overcomes the elastic force of the torsion spring 80, so that the locking component 60 rotates around the third rotating shaft 7002 to release the locking state of the locking component 60 and the curved rod 50. The locking component 60 and the curved rod 50 can move freely. At this time, the cabinet door limiting mechanism is in a state as shown in FIG. Fig.11 The cabinet door 10 can move freely. When force is applied to the cabinet door, the cabinet door limit mechanism returns to the free state as shown. Fig.10 In the folded state, the cabinet door 10 can be closed.

[0041] The energy storage cabinet of the utility model is provided with a cabinet door limiting mechanism between the cabinet door and the box body, which can limit the opening angle of the cabinet door, and at the same time can keep the cabinet door at the maximum opening angle without being blown down or closed by the wind, thereby providing a safe operating environment for the operator, and will not be injured by the sudden closing of the cabinet door. By setting a locking component to lock the activities of the bent rod and the connecting rod mechanism to achieve the purpose of convenient operation, the cabinet door limiting mechanism of the energy storage cabinet of the utility model has a simple structure and is easy to operate, which solves the problem that the cabinet door is easily closed abnormally in the prior art, and improves the operational safety of the energy storage cabinet.
