Description

Technical Field

[0001] This invention relates to an energy storage cabinet, and more specifically, to a control structure for a hinge rod in the door of an energy storage cabinet. Background Technology

[0002] Energy storage cabinets mainly convert electrical energy into another form of energy through energy storage devices and store it. When needed, they convert it back into electrical energy through converters and transmit it to the electrical equipment that needs it through the power grid.

[0003] In outdoor settings, strong winds can cause cabinet doors to swing violently without restraint, potentially impacting the cabinet or operators, leading to equipment malfunctions and safety accidents.

[0004] Therefore, a design is needed to restrict the rotation of the cabinet doors. Summary of the Invention

[0005] The purpose of this invention is to provide a control structure for the hinge rod in the door of an energy storage cabinet, which controls the maximum opening range of the cabinet door and can limit the automatic rotation of the cabinet door in the closing direction, thereby achieving the rotation design of the cabinet door.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A control structure for a hinge rod in an energy storage cabinet door includes a cabinet body and a cabinet door. A hinge rod is hinged inside the cabinet body, and a slide rail is provided inside the cabinet door. The other end of the hinge rod slides within the slide rail. When the cabinet door is opened to its maximum angle, the end of the hinge rod abuts against the end of the slide rail to limit the cabinet door from opening further.

[0007] Preferably, the angle when the cabinet door is opened to its maximum is 'a', and the range of 'a' is 90-120 degrees.

[0008] Preferably, a partition cover is installed inside the cabinet door.

[0009] Preferably, a power inlet is installed inside the cabinet, located at the bottom of the cabinet and near the hinge rod; a baffle is installed inside the cabinet door to prevent the hinged end of the hinge rod from hitting the terminal of the power inlet after disengagement.

[0010] Preferably, the side facing downwards and the side facing the door of the partition cover are both open; the other four sides of the partition cover are baffles, and the side has a clearance cut, which is used for the hinge rod to extend when the cabinet door is closed.

[0011] Preferably, the cabinet body is provided with a limiting closure component; when the cabinet door is opened, the cabinet door rotates in one direction to open; after the cabinet door is opened, the limiting closure component locks the cabinet door in one direction to prevent the cabinet door from rotating in the closing direction; the cabinet body door frame is provided with an unlocking component, which includes an unlocking block and a reset block; when the user presses the unlocking block, the limiting closure component retracts its locking obstruction of the cabinet door; when the cabinet door is closed, the reset block is triggered, the limiting closure component returns to the one-way locking obstruction state, and the unlocking block pops out to wait for pressing.

[0012] Preferably, the limiting closure assembly includes a ratchet and a pawl, with the ratchet fixed to the hinge bar; the rotation axis of the ratchet and the rotation axis of the hinge bar are the same axis; the pawl is rotatably connected to the partition cover, and the pawl is connected to a torsion spring to push itself to maintain contact with the ratchet.

[0013] Preferably, the cabinet includes a lower door frame with an interior space; for the unlocking component, the unlocking block slides on the door frame, with one end of the unlocking block extending out of the cabinet door and the other end extending into the cabinet; a push rod is fixed to one end of the unlocking block inside the cabinet, and the push rod is located between a ratchet and a pawl; pressing the unlocking block causes the unlocking block to move the push rod toward the pawl and disengage the pawl and ratchet.

[0014] Preferably, for the unlocking component, the reset block slides vertically on the unlocking block, and an outlet is provided at the upper end of the lower door frame. The reset block is inside the lower door frame and slides out from the outlet. The unlocking block is provided with an ejector spring, which gives the reset block a tendency to extend out of the outlet. The lower door frame is provided with a reset spring, which gives the push rod a tendency to move away from the pawl. In the reset state, under the push of the reset spring, the upper end of the reset block abuts against the inner side of the lower door frame, and the side of the reset block blocks the inner side of the lower door frame to restrict the movement of the unlocking block to the outside of the cabinet. At this time, the push rod, pawl, and ratchet maintain a gap. During the unlocking action, pressing the unlocking block causes the unlocking block to move the reset block to the outlet position. The reset block rises and engages with the outlet to restrict the movement of the unlocking block. At this time, the unlocking block drives the push rod to separate the pawl and ratchet.

[0015] Preferably, the upper surface of the reset block is an inclined surface; when the cabinet door is closed on the lower door frame, the lower edge of the cabinet door presses against the inclined surface to push the reset block into the lower door frame; the reset block that enters the lower door frame, under the drive of the reset spring, is in a state where the upper end of the reset block abuts against the inner side of the lower door frame.

[0016] In summary, the present invention has at least one of the following beneficial effects: 1. The opening and closing control is precise, limiting the maximum opening angle of the cabinet door to 90-120°. The one-way locking completely eliminates the cabinet door from swinging or self-closing under strong outdoor winds, thus eliminating the safety hazards caused by cabinet door impacts to people.

[0017] 2. The partition covers form a physical isolation barrier to prevent the hinge rod from hitting the power inlet terminal when it loosens / detaches, thus avoiding short circuits and leakage and improving the electrical safety level of the energy storage cabinet.

[0018] 3. Ease of operation: The cabinet door can be opened in one direction and is protected against self-closing, making it suitable for outdoor high-wind scenarios. The lock can be released by pressing the unlocking block with one button, and it will automatically reset when the cabinet door is closed. The locking mechanism does not require manual adjustment and can be operated quickly by a single person. Moreover, this solution is a purely mechanical structure with no electrical control components, making it suitable for outdoor energy storage cabinet scenarios and highly feasible overall.

[0019] 4. For the first time, the four core functions of precise opening limit, one-way windproof locking, electrical safety protection, and automatic door closing reset are integrated into a single hinge rod control structure, subverting the traditional design concept of energy storage cabinet hinges; using the mechanical pressure of the cabinet door closing to passively trigger the reset, no electrical control or manual operation is required. Through the self-guiding of the reset block inclined surface and the linkage of double springs, the passive intelligent control of "reset when the door is closed" is realized.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: A control structure for the hinge rod in the door of an energy storage cabinet, referring to... Figures 1-5 It includes a cabinet body 1 and a cabinet door 11, with a lower door frame 12 at the bottom of the cabinet body 1.

[0024] A hinge rod 21 is hinged to the inside of the cabinet body 1. An angle steel plate is welded to the inside of the cabinet door 11. A straight slide rail 22 is provided on the angle steel plate. A slider 26 is provided at the end of the hinge rod 21 away from the cabinet body 1. The slider 26 is embedded in the slide rail 22 and forms a sliding fit with the slide rail 22.

[0025] When the cabinet door 11 is opened to its maximum angle, the slider 26 abuts against the end of the slide rail 22, forming a mechanical limit, which limits the maximum opening angle a of the cabinet door 11 to the range of 90°-120°, so as to avoid structural damage caused by excessive opening of the cabinet door 11. In this embodiment, a is 110 degrees.

[0026] Reference Figure 3 and Figure 4 The hinge rod 21 and the hinge end of the cabinet 1 are fastened together by a bushing 23, a bolt 24 and a nut 25 to ensure the smoothness of the hinge rotation and the structural strength. The bushing 23 is inserted into the hole of the hinge rod 21, the bolt 24 is inserted into the bushing 23, and the lower end of the bolt 24 is connected to the nut 25. Nut 25 is welded to the bridge plate, and the bridge plate is fixed to the door body.

[0027] Therefore, once the bolt 24 and nut 25 are tightened, the hinge rod 21 can rotate smoothly around the bushing 23.

[0028] Figure 2 and Figure 3The power inlet section 3 is installed at the bottom of the cabinet 1 near the hinge end of the hinge rod 21. The power inlet section 3 is provided with a terminal 31. The external cable extends from the bottom of the cabinet and is then connected to the terminal 31.

[0029] Figure 3 and Figure 4 A partition cover 4 is fixedly installed on the inside of the cabinet door 11 and the cabinet body 1. The partition cover 4 covers the outside of the hinge end of the hinge rod 21 to form a physical protective barrier. The side of the partition cover 4 facing downward and the side facing the door are open, and the other four sides are equipped with baffles 41. The side baffles 41 have clearance cuts 42. Figure 5 When the cabinet door 11 is closed, the hinge rod 21 extends into the partition cover 4 through the clearance cut 42. When the cabinet door 11 is opened, the hinge rod 21 rotates out along the clearance cut 42. The partition cover 4 can effectively prevent the hinge rod 21 from hitting the terminal 31 when it becomes loose or detached, thus eliminating potential electrical safety hazards.

[0030] The partition cover 4 forms a physical isolation barrier to prevent the hinge rod 21 from hitting the terminal 31 of the power inlet section 3 when it becomes loose or detached, thus avoiding short circuits and leakage and improving the electrical safety level of the energy storage cabinet.

[0031] The clearance slit 42 provides clearance space when the cabinet door 11 is closed and the hinge rod 21 rotates, ensuring that the cabinet door 11 closes smoothly.

[0032] Example 2: A control structure for the hinge rod in the door of an energy storage cabinet, referring to... Figures 6-13 .

[0033] Specifically: Figure 6 The lower door frame 12 has reserved assembly space inside, providing room for the installation and movement of internal components.

[0034] Figures 7-8 The description includes a limiting closure assembly comprising a ratchet 61 and a pawl 62.

[0035] The ratchet 61 is hollow and welded to the upper surface of the hinge rod. Therefore, the ratchet 61 is coaxially fixed on the hinge axis of the hinge rod 21, and the rotation axis of the ratchet 61 coincides with the hinge axis of the hinge rod 21.

[0036] Pawl 62 is rotatably connected to the partition cover 4. A support rod is welded to the inner baffle of the partition cover 4. The pivot of pawl 62 is fixed to the support rod, and pawl 62 rotates around the support rod. Pawl 62 is equipped with a torsion spring 71 (the position of the torsion spring is shown in the figure). Figure 12 The torsion spring 71 continuously applies an elastic force to the pawl 62, so that the pawl 62 always remains in meshing contact with the ratchet 61.

[0037] When cabinet door 11 is opened, hinge rod 21 drives ratchet 61 to rotate in the forward direction, and pawl 62 slides smoothly along the tooth surface of ratchet 61 without obstructing the opening action of cabinet door 11; when cabinet door 11 is subjected to external force or wind force and attempts to close in the reverse direction, pawl 62 engages with the tooth groove of ratchet 61 to form a one-way locking block, completely restricting cabinet door 11 from rotating in the closing direction, which is suitable for use in outdoor windy conditions; in windy weather, when the user is performing maintenance at the location of cabinet door 11, cabinet door 11 will not automatically hit the user.

[0038] Figures 9-13 The unlocking components are described as including an unlocking block 51, a push rod 52, a reset block 53, an ejection spring 72, and a reset spring 73.

[0039] The lower door frame 12 is a rectangular tube with internal installation space; The unlocking block 51 is slidably mounted on the lower door frame 12. Specifically, the lower door frame 12 has a horizontal sliding hole, and the unlocking block 51 slides in the sliding hole, so the unlocking block 51 moves in the inward and outward directions on the lower door frame 12.

[0040] One end of the unlocking block 51 extends out of the cabinet door 11 for manual pressing, and the other end extends into the cabinet through the lower door frame 12 and is fixedly connected to the vertical push rod 52. The vertical push rod 52 is located in the gap between the ratchet 61 and the pawl 62.

[0041] The reset block 53 is vertically slidably mounted on the upper part of the unlocking block 51. Specifically, the upper surface of the unlocking block 51 has a vertical hole, and the reset block 53 slides vertically in the vertical hole. Since the vertical hole is located inside the lower door frame 12, the main body of the reset block 53 remains inside the lower door frame 12 and moves.

[0042] An outlet 13 is provided at the upper end of the lower door frame 12 for the reset block 53 to extend out; an ejector spring 72 is installed at the bottom of the vertical hole of the unlocking block 51, and the ejector spring 72 applies an upward elastic force to the reset block 53, so that the reset block 53 maintains the tendency to extend out of the outlet 13.

[0043] A mounting groove is welded to the side of the lower door frame 12 facing the inside of the cabinet. A reset spring 73 is installed in the mounting groove. The reset spring 73 is kept in a compressed state. The reset spring 73 abuts against the unlocking block 51. The reset spring 73 applies an elastic force away from the pawl 62 to the push rod 52 to ensure the reliability of unlocking and reset.

[0044] The upper surface of the reset block 53 is formed into a slope 54. When the cabinet door 11 is closed, the lower edge of the cabinet door 11 presses against the slope 54, pushing the reset block 53 downward into the lower door frame 12 to complete the reset trigger.

[0045] In this embodiment, the working process of the energy storage cabinet door hinge rod control structure is divided into four stages: opening limit, one-way locking, unlocking and closing, and automatic reset. 1. During the opening limit stage, the cabinet door 11 is manually pulled open, the hinge rod 21 rotates with the cabinet door 11, and the slider 26 slides along the slide rail 22 in a directional manner; when the cabinet door 11 is opened to 110°, the slider 26 touches the end of the slide rail 22, and the mechanical limit prevents the cabinet door 11 from continuing to open, thus completing the opening degree control.

[0046] 2. During the one-way locking stage, when the cabinet door 11 is opened, the hinge rod 21 drives the ratchet 61 to rotate synchronously, and the pawl 62 continuously engages the ratchet 61 under the action of the torsion spring 71, allowing the cabinet door 11 to open in one direction only and prohibiting it from closing in the opposite direction, thus achieving windproof and anti-sway locking.

[0047] 3. During the unlocking and closing phase, manually press the unlocking block 51. The unlocking block 51 drives the push rod 52 to move towards the pawl 62. The push rod 52 pushes the pawl 62 to overcome the elastic force of the torsion spring 71 and separate from the ratchet 61, thus releasing the one-way lock. At this time, the cabinet door 11 can rotate freely in the closing direction to complete the closing operation. When the door is unlocked and closed, the following actions occur simultaneously: the reset block 53 moves to the outlet 13 position, the push spring 72 pushes the reset block 53 to move upward and extend out of the outlet 13, the reset block 53 is stuck in the outlet 13 to keep the pawl 62 and ratchet 61 separated, and the inclined surface 54 of the reset block 53 extends out to wait for the cabinet door 11 to close.

[0048] 4. During the automatic reset phase, when the cabinet door 11 is closed to the lower door frame 12, the lower edge of the cabinet door 11 presses against the inclined surface 54 of the reset block 53, and the reset block 53 retracts into the lower door frame 12. The elastic force of the reset spring 73 is sufficient to push the inclined surface 54 to slide into the lower door frame 12 along the edge of the outlet 13 until the reset block 53 is attached to the inner wall of the lower door frame 12. The reset spring 73 pushes the unlocking block 51 and the push rod 52 to reset. The pawl 62 re-engages the ratchet 61 under the action of the torsion spring 71. The unlocking block 51 automatically pops out, restoring the one-way locking state, and waits for the next operation.

[0049] The above structure and working process realize full-function control of precise door opening limit, one-way windproof locking, one-button unlocking, and automatic reset when the door is closed. The pure mechanical structure has no electronic components, making it suitable for long-term stable use of outdoor energy storage cabinets. At the same time, the partition cover provides electrical safety protection, improving the overall safety of the energy storage cabinet.

[0050] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
