[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0041] See also Figures 1 to 12 As shown, the present invention provides an energy storage and power distribution safety cabinet based on multiple protection mechanisms, including a cabinet body 1, a protection part 2 is rotatably provided at the opening of the cabinet body 1, and the protection part 2 is used to close the opening of the cabinet body 1, so that the interior of the cabinet body 1 forms a closed space to prevent the electrical components inside the cabinet body 1 from being damaged by external influences:

[0042] A locking portion 3 is provided in the middle of the inner side of the cabinet 1, and the locking portion 3 can lock and unlock the protection portion 2 by rotating;

[0043] A docking portion 4 is also provided in the middle of the inner side of the cabinet 1. The movement of the docking portion 4 enables the electrical components inside the cabinet 1 to be docked and separated. At the same time, one side of the docking portion 4 cooperates with the inside of the locking portion 3, so that the locking portion 3 can perform subsequent operations only after the docking portion 4 performs relevant operations.

[0044] The locking part 3 includes a mounting seat 301, which is fixedly connected to the middle part of the inner side of the cabinet 1, and a locking rod 302 is rotatably connected inside the mounting seat 301. A limit block 303 is fixedly provided at one end of the locking rod 302, and the interior of the limit block 303 cooperates with one side of the docking part 4. A fixed block 304 is slidably provided inside the mounting seat 301, and the fixed block 304 cooperates with the middle part of the locking rod 302. An elastic extrusion piece 305 is provided between the fixed block 304 and the mounting seat 301, and an extrusion plate 306 is fixedly provided at the other end of the locking rod 302, and the extrusion plate 306 cooperates with the interior of the protective part 2, and an unlocking handle 307 is fixedly provided at one end of the locking rod 302.

[0045] It should be noted that if Figure 7 As shown, the limit block 303 is divided into a rotating section, a sliding section and an unlocking section. The rotating section and the unlocking section inside the limit block 303 are slots (the angle of the slot is forty-five degrees), and the sliding section is a horizontal guide slot, wherein the limit plate 403 (strip plate) is placed inside the slot of the rotating section in the initial state.

[0046] Specifically, when it is necessary to operate the interior of the cabinet 1, the unlocking handle 307 is in a vertical state, and the limit plate 403 contacts the upper wall of the rotating section of the limit block 303. First, the unlocking handle 307 needs to be rotated upward, and the unlocking handle 307 drives the locking rod 302, the limit block 303 and the extrusion plate 306 to rotate together. When the unlocking handle 307 is rotated forty-five degrees, the other end of the limit plate 403 contacts the lower wall of the rotating section of the limit block 303, and the other end of the limit plate 403 is at the junction of the rotating section and the sliding section of the limit block 303. The limit plate 403 loses the structural limit inside the rotating section of the limit block 303, so that the limit plate 403 can slide into the interior of the sliding section. At this time, the protective part 2 is still locked by the extrusion plate 306 and cannot be opened;

[0047] Then, the docking part 4 is rotated to make the docking part 4 move horizontally inside the cabinet 1 to complete the separation and assembly of the electrical appliance and the mains. At this time, the movement of the docking part 4 releases the limit of the limit block 303;

[0048] When the electrical appliances inside the cabinet 1 are disconnected from the mains and powered off, it can ensure that the operator is in a power-free operating environment after opening the cabinet; when the electrical appliances inside the cabinet 1 are connected to the mains, the power connection part is far away from the operator and is in a closed environment, which can further protect the operator from the risk of electric shock;

[0049] Then, the unlocking handle 307 is rotated continuously, and the unlocking handle 307 drives the locking rod 302, the limit block 303 and the extrusion plate 306 to rotate continuously. At this time, the limit block 303 is retracted into the interior of the mounting seat 301, so that the protection part 2 loses the fixation of the limit block 303, and the unlocking handle 307 is at a 90-degree angle.

[0050] Then the protection part 2 is rotated open to expose the interior of the cabinet 1 for operation. Since the electrical equipment inside the cabinet 1 is in a power-off state at this time, the operator can avoid the risk of electric shock during operation inside the cabinet 1, thereby ensuring the safety of the staff.

[0051] See also Figure 7As shown, a limiting groove is provided inside the limiting block 303, and the inside of the limiting groove is divided into three parts: a rotating section, a sliding section, and an unlocking section. In the initial state, one end of the docking portion 4 is inside the rotating section. As the limiting block 303 rotates, one end of the docking portion 4 enters the junction of the rotating section and the sliding section. At this time, the limiting block 303 is restricted by the structure of the docking portion 4 and cannot rotate.

[0052] Then one end of the docking part 4 enters the interior of the sliding section, and at this time, one end of the docking part 4 moves horizontally inside the sliding section until the docking part 4 enters the interior of the unlocking section. During this period, the limit block 303 is still unable to rotate due to the structural restriction of the docking part 4. At this time, the docking part 4 can connect and disconnect the electrical appliance with the mains due to sliding;

[0053] Then one end of the docking part 4 enters the unlocking section, and the limit block 303 can continue to rotate. Through the cooperation of the rotating section, sliding section and unlocking section inside the limit groove and the docking part 4, a multi-stage operation process of the limit block 303 and the docking part 4 is realized, and the cabinet 1 cannot be opened when the docking part 4 is not powered off, and the docking part 4 is in a closed environment when power is supplied.

[0054] See also Figure 7 As shown, the rotation section and the unlocking section of the internal limit groove of the limit block 303 are arc-shaped grooves of 45 degrees, so that the limit block 303 will be restricted by the structure of the docking part 4 and cannot move after rotating 45 degrees inside the rotation section and the unlocking section;

[0055] At the same time, when the unlocking handle 307 is rotated to 90 degrees and is in a horizontal state, the unlocking handle 307 is located between the protective plates 201 , which can prevent the unlocking handle 307 from affecting the opening and closing of the protective plates 201 .

[0056] See also Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the middle part of the locking rod 302 is set to a polygon, and the polygon is in contact with one end of the fixed block 304. The fixed block 304 is squeezed by the elastic extrusion piece 305, so that the fixed block 304 always applies pressure to the middle part of the locking rod 302. Since the middle part of the locking rod 302 is set to a polygon, when the locking rod 302 rotates and stops, the fixed block 304 can always apply pressure to the middle part of the locking rod 302, and the friction between the fixed block 304 and the locking rod 302 is increased by the outer edge of the polygon, which can prevent the locking rod 302 from rotating without being subjected to force.

[0057] See also Figures 2 to 4As shown, the protection part 2 includes a protection plate 201, a locking block 202, a support rod 203 and an elastic reset member 204. The protection plate 201 is provided with two upper and lower blocks, and one end of the protection plate 201 is rotatably connected to the opening of the cabinet 1. There are two locking blocks 202, and the two locking blocks 202 are respectively slidably arranged inside the upper and lower ends of the corresponding protection plate 201, and the two locking blocks 202 are in a vertical corresponding state with the extrusion plate 306. The two ends of the support rod 203 are fixedly connected to the corresponding two locking blocks 202, and the elastic reset member 204 is arranged between the support rod 203 and the protection plate 201;

[0058] When the squeezing plate 306 is extended, the unlocking handle 307 is in an inclined state or a vertical state, and the squeezing plate 306 squeezes the corresponding locking block 202 to slide inside the protective plate 201. The movement of the locking block 202 squeezes another locking block 202 through the support rod 203 to move out and snap into the inside of the cabinet 1, thereby limiting and fixing the protective plate 201 to prevent the protective plate 201 from being opened;

[0059] When the extrusion plate 306 shrinks into the interior of the mounting base 301, the unlocking handle 307 is in a horizontal state, and the locking block 202 loses the squeezing of the extrusion plate 306. At this time, the elastic reset member 204 squeezes the support rod 203 to move, so that the support rod 203 drives the other locking block 202 to shrink into the interior of the protective plate 201, thereby releasing the locking block 202 from locking the protective plate 201.

[0060] See also Figure 4 As shown, both ends of the extrusion plate 306 are configured to be arc-shaped, and the arc shape matches the locking block 202. When the extrusion plate 306 rotates with the locking rod 302, the arc surfaces at both ends can improve the stability of the extrusion plate 306 when extruding the locking block 202.

[0061] See also Figures 5 to 12 As shown, the docking portion 4 includes a rotating screw 401, a sliding seat 402, a limiting plate 403, a docking plate 404, a pulling rod 405, a rotating block 406 and a locking slider 407, the rotating screw 401 is rotatably arranged inside the mounting seat 301, the interior of the sliding seat 402 is threadedly connected to the outer edge of the rotating screw 401, one end of the limiting plate 403 is fixedly connected to one side of the sliding seat 402, and the other end of the limiting plate 403 is slidably connected to the inside of the limiting groove of the limiting block 303, the docking plate 404 is fixedly connected to the inner side of the cabinet 1, and the docking plate 404 corresponds horizontally to the sliding seat 402, one end of the pulling rod 405 is slidably connected to the inside of the rotating screw 401, the rotating block 406 is fixedly connected to one end of the pulling rod 405, the locking slider 407 is slidably arranged inside the mounting seat 301, and the two ends of the locking slider 407 are respectively matched with the corresponding pulling rod 405 and the outer edge of the locking rod 302;

[0062] In the initial state, the rotating block 406 is inside the mounting seat 301, the sliding seat 402 and the docking plate 404 are in a splicing state, the other end of the limit plate 403 is inside the rotating section of the limit block 303, and the pulling rod 405 is in a fixed state squeezed and limited by the locked slider 407;

[0063] After the limit block 303 rotates 45 degrees in the first stage, the other end of the limit plate 403 enters the intersection of the rotation section and the sliding section of the limit block 303, and the locking rod 302 releases the squeezing and fixing of the locking slider 407. At this time, by pulling the rotating block 406, the rotating block 406 is moved out of the mounting seat 301, and the pulling rod 405 is driven to slide and extend inside the rotating screw 401, at this time, the pulling rod 405 is released and the rotating block 406 is moved out;

[0064] Then, by rotating the pulled-out rotating block 406, the pulling rod 405 and the rotating screw 401 are driven to rotate together, and the rotation of the rotating screw 401 drives the sliding seat 402 connected by the outer thread to move horizontally, so that the sliding seat 402 is gradually separated from the docking plate 404, so that the electrical components at the sliding seat 402 lose power supply, and at the same time, the limit plate 403 also moves with the movement of the sliding seat 402. At this time, the limit plate 403 is in the internal movement of the sliding section of the limit block 303. When the sliding seat 402 stops moving, the limit plate 403 enters the internal unlocking section of the limit block 303. Only then can the unlocking handle 307 be continuously rotated to drive the limit block 303 to rotate upward until the unlocking handle 307 is in a horizontal state;

[0065] It should be noted that the sliding section of the limit block 303 and the sliding seat 402 move horizontally at the outer edge of the rotating screw 401 for the same distance.

[0066] See also Fig.10 As shown, a guide groove is provided inside the rotating screw 401, and the inside of the guide groove cooperates with the outer edge of one end of the pulling rod 405. The guide groove provides a guide for the horizontal movement of the pulling rod 405. At the same time, during the rotation of the pulling rod 405, the rotating screw 401 can be driven to rotate together due to the structural restriction of the guide groove.

[0067] See also Figures 5 to 10 as well as Fig.12As shown, a limiting ring groove is provided on the outer edge of the pulling rod 405 which matches with one end of the locking slider 407. When the pulling rod 405 is retracted into the mounting seat 301, the limiting ring groove corresponds to the locking slider 407 horizontally. When the pulling rod 405 is retracted into the interior of the rotating screw 401, the limiting ring groove matches with the locking slider 407 horizontally. When the locking rod 302 is in the initial state, the locking rod 302 squeezes the locking slider 407 so that one end of the locking slider 407 is stuck in the interior of the limiting ring groove. At this time, the pulling rod 405 is limited by the locking slider 407 and is in a locked state and cannot move. At the same time, the rotating block 406 is also in a limited state inside the mounting seat 301. At this time, the pulling rod 405 in the initial state is locked and cannot be rotated by the rotating block 406 and is in a limited state.

[0068] When the locking rod 302 rotates, the locking slider 407 loses the squeezing of the locking rod 302. At this time, when the pulling rod 405 extends, it can squeeze the locking slider 407 to move toward the locking rod 302. At the same time, the rotating block 406 also moves out of the interior of the mounting seat 301. At this time, the rotation of the rotating block 406 can drive the pulling rod 405 to rotate together.

[0069] See also Figures 5 to 10 as well as Fig.12 As shown, the other end of the locking rod 302 is provided with a locking ring groove, the interior of the locking ring groove matches with the other end of the locking slider 407, a protruding locking knot is provided inside the locking ring groove, and the locking knot is arranged at a 90-degree angle with the unlocking handle 307. When the locking rod 302 is in the initial state, the locking knot squeezes the locking slider 407 to move into the inner limit ring groove of the pulling rod 405, thereby fixing the pulling rod 405.

[0070] When the locking rod 302 is rotated by the unlocking handle 307, the locking knot changes its squeezing direction, and the pulling rod 405 loses the squeezing limit of the locking slider 407 and can be pulled out;

[0071] At the same time, when the pull rod 405 is in the pulled-out state, the locking slider 407 will be limited by the pull rod 405. At this time, the locking rod 302 will be restricted by the structure of the locking knot when rotating and cannot continue to rotate. The locking rod 302 needs to rotate to the initial state to meet two preconditions:

[0072] First, the pulling rod 405 is retracted into the interior of the rotating screw 401, at which time the locking ring groove, the limiting ring groove locking slider 407 are in a horizontal corresponding state;

[0073] Secondly, the limiting plate 403 is located inside the rotation section of the limiting block 303. The locking rod 302 continues to rotate to enable the locking knot to squeeze and push the locking slider 407 to snap into the limiting ring groove of the pulling rod 405, and the locking rod 302 can rotate at the same time.

[0074] Only after the above two preconditions are met can the unlocking handle 307 be turned downward to put the unlocking handle 307 in a vertical state.

[0075] The working principle of the present invention is as follows: when it is necessary to operate the interior of the cabinet 1, the unlocking handle 307 is in a vertical state, and the limit plate 403 contacts the upper wall of the rotation section of the limit block 303. First, the unlocking handle 307 needs to be rotated upward, and the unlocking handle 307 drives the locking rod 302, the limit block 303 and the extrusion plate 306 to rotate together. When the unlocking handle 307 is rotated forty-five degrees, the other end of the limit plate 403 contacts the lower wall of the rotation section of the limit block 303, and the other end of the limit plate 403 is at the junction of the rotation section and the sliding section of the limit block 303. The limit plate 403 loses the structural limit inside the rotation section of the limit block 303, so that the limit plate 403 can slide into the interior of the sliding section. At this time, the protective part 2 is still locked by the extrusion plate 306 and cannot be opened.

[0076] Then, the docking part 4 is rotated to make the docking part 4 move horizontally inside the cabinet 1 to complete the separation and assembly of the electrical appliance and the mains. At this time, the movement of the docking part 4 releases the limit of the limit block 303;

[0077] When the electrical appliances inside the cabinet 1 are disconnected from the mains and powered off, it can ensure that the operator is in a power-free operating environment after opening the cabinet; when the electrical appliances inside the cabinet 1 are connected to the mains, the power connection part is far away from the operator and is in a closed environment, which can further protect the operator from the risk of electric shock;

[0078] Then, the unlocking handle 307 is rotated continuously, and the unlocking handle 307 drives the locking rod 302, the limit block 303 and the extrusion plate 306 to rotate continuously. At this time, the limit block 303 is retracted into the interior of the mounting seat 301, so that the protection part 2 loses the fixation of the limit block 303, and the unlocking handle 307 is at a 90-degree angle.

[0079] Then the protection part 2 is rotated open to expose the interior of the cabinet 1 for operation. Since the electrical components inside the cabinet 1 are all in a closed state at this time, the operator can avoid the risk of electric shock during operation inside the cabinet 1, thereby ensuring the safety of the staff.

[0080] The above is only a preferred embodiment of the present invention.
