Technical Field

[0003] The present application relates to the technical field of energy storage devices, and in particular to a limiting mechanism and an energy storage device. Background Art

[0004] In related art, an electrical cabinet consists of a housing and a door hinged to the housing. To control the door's opening range, a limiter mechanism is typically used to connect the door and the housing to restrict its opening. However, when the worker opens the door to perform work, the limiter mechanism fails to lock the door in place, making it susceptible to external forces and hindering the worker's work.

[0005] Summary of the Invention

[0006] In view of the above problems, the purpose of the embodiments of the present application is to provide a limiting mechanism and an energy storage device, which can improve the technical problem that the limiting structure cannot lock the position of the door body.

[0010] A connecting shaft, slidingly engaged with the guide structure;

[0011] a connecting arm connected to the connecting shaft;

[0012] The connecting seat is further provided with a locking position for locking the connecting shaft in the length direction of the connecting seat.

[0013] By adopting the sliding cooperation between the connecting shaft and the guide structure, when the connecting arm and the connecting seat are unfolded, the connecting shaft can slide along the guide structure to adapt to the unfolding angle of the connecting arm and the connecting seat; when the connecting shaft slides to the locking position, the locking position can lock the position of the connecting shaft, so that the position of the connecting shaft remains stable, and the unfolding angle of the connecting arm and the connecting seat is locked, so as to lock the door opening and prevent the door opening from changing during operation.

[0014] In one embodiment, the guide structure is a strip-shaped hole.

[0015] By adopting the above technical means, the connecting shaft can be guided to slide along the length direction of the connecting seat, and the connecting shaft can be allowed to rotate in the strip hole to automatically adapt to changes in the expansion angle of the connecting arm and the connecting seat.

[0018] By adopting the above-mentioned technical means, when the first shaft segment slides to the limiting hole, the connecting shaft slides along the depth direction of the limiting hole until the second shaft segment is limited in the limiting hole, and the limiting hole limits the second shaft segment from continuing to slide along the strip hole, so that the position of the connecting shaft in the length direction of the connecting seat remains stable, and the expansion angle of the connecting arm and the connecting seat remains relatively stable; after the connecting shaft is reset, the second shaft segment leaves the limiting hole, and the first shaft segment enters the limiting hole, and the first shaft segment can slide into the strip hole again, so as to continue to adjust the position of the connecting shaft and adjust the expansion angle of the connecting arm and the connecting seat.

[0019] In one embodiment, a third shaft segment is provided at one end of the second shaft segment away from the first shaft segment, and a diameter of the third shaft segment is larger than a diameter of the limiting hole.

[0020] By adopting the above-mentioned technical means, when the connecting shaft slides to the second shaft segment and is limited in the limiting hole, since the diameter of the third shaft segment is larger than the diameter of the limiting hole, it can prevent the connecting shaft from sliding out of the limiting hole from the end of the second shaft segment away from the first shaft segment, thereby preventing the connecting shaft from separating from the connecting seat.

[0021] In one embodiment, one end of the first shaft segment away from the second shaft segment is connected to the connecting arm.

[0031] In one embodiment, a fastener for connecting with the box body is installed on the first side panel.

[0032] By adopting the above technical means, the first side panel can be conveniently connected and fixed to the door body.

[0033] In one embodiment, the connecting arm is located on the other side of the connecting plate along the thickness direction.

[0034] By adopting the above technical means, the first side plate and the second side plate can be prevented from interfering with the rotation of the connecting arm, which is beneficial to reducing the distance between the connecting arm and the connecting plate, reducing the length of the connecting shaft, and improving the stability between the connecting arm and the connecting seat.

[0035] In one embodiment, the connecting arm is provided with a reinforcing rib, and the reinforcing rib is arranged along the length direction of the connecting arm.

[0036] By adopting the above technical means, the bending strength of the connecting arm can be enhanced.

[0037] In one embodiment, the connecting arm includes a first plate segment connected to the connecting shaft, a second plate segment connected to an end of the first plate segment away from the connecting shaft, and a third plate segment connected to an end of the second plate segment away from the first plate segment, and the second plate segment is inclined from an end of the first plate segment away from the connecting shaft to an end of the third plate segment close to the connecting shaft toward a direction away from the connecting seat.

[0038] By adopting the above-mentioned technical means, when the connecting arm is folded to the side of the connecting seat, the distance between the end of the connecting arm away from the connecting shaft and the connecting seat can be increased, thereby avoiding collision between the end of the connecting arm away from the connecting shaft and the connecting seat when the door body is closed.

[0039] In one embodiment, the reinforcing rib is located on a side of the third plate segment close to the connecting seat, and the reinforcing rib is connected to the second plate segment and the third plate segment.

[0041] In one embodiment, the height of the reinforcing rib gradually decreases from an end of the second plate segment close to the first plate segment to an end of the third plate segment away from the first plate segment.

[0042] By adopting the above technical means, when the connecting arm rotates relative to the connecting seat, it is helpful to reduce the friction between the reinforcing rib and the connecting plate, and it is also helpful to demould the connecting arm during casting.

[0043] In one embodiment, each side surface of the reinforcing rib in the width direction is inclined toward the middle of the reinforcing rib in the width direction from the side of the reinforcing rib close to the third plate segment to the side of the reinforcing rib away from the first plate segment.

[0045] In one embodiment, a rotating shaft for hinged connection with the box body is installed at one end of the connecting arm away from the connecting shaft.

[0046] By adopting the above technical means, the connecting arm and the door body can be easily hinged.

[0047] In one embodiment, a shaft sleeve is sleeved on the rotating shaft, and the connecting arm is slidably sleeved on the shaft sleeve.

[0048] By adopting the above technical means, it is possible to facilitate the sliding of the connecting arm along the sliding sleeve, so that the connecting shaft can slide along the depth direction of the limiting hole.

[0049] In one embodiment, one end of the sleeve close to the connecting seat protrudes from a side of the connecting arm close to the connecting seat; and / or,

DETAILED DESCRIPTION

[0064] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0065] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0066] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0067] In the description of this application, "a plurality of" means more than two, and unless otherwise specifically defined, "more than two" includes two. Accordingly, "a plurality of groups" means more than two groups, including two groups.

[0068] In the description of this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0069] In the description of this application, the term "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists, A and B exist at the same time, and B exists. In addition, in this application, the character " / " generally indicates that the related objects are in an "or" relationship.

[0070] In related art, an electrical cabinet includes a housing and a door hinged to the housing. Workers need to open the door when performing operations. When the door is opened too wide, the door and the housing near the hinged joint are prone to collision. When a worker collides with the door on the side away from the hinged joint, the force arm at the collision point between the worker and the door is much longer than the force arm at the collision point between the door and the housing. This can easily damage the hinged joint between the door and the housing, causing local deformation of the door and the housing, which in turn affects the door's opening and closing.

[0071] To this end, a limiter mechanism can be installed between the door and the box to limit the door's opening range, preventing it from opening too wide and colliding with the box, protecting the hinged joint between the door and the box, and preventing deformation. However, during operation, workers often come into contact with the door, causing it to open and close within the opening range defined by the limiter mechanism, thus interfering with their work.

[0072] Based on the above considerations, some embodiments of the present application provide a limiting mechanism, please refer to Figures 1 to 6, the limiting mechanism 100 includes a connecting seat 10, a connecting shaft 20 and a connecting arm 30, and the connecting seat 10 is provided with a guide structure 1101 and a locking position 1102, and the connecting shaft 20 slides with the guide structure 1101; the locking position 1102 is used to lock the position of the connecting shaft 20 along the length direction X of the connecting seat 10 when the connecting arm 30 is unfolded (as shown in Figures 3 and 6). It can be connected to the door body 300 through the connecting seat 10, and the connecting arm 30 is connected to the box body 200. When the door body 300 is opened, the connecting seat 10 swings outward, and the connecting arm 30 pulls the connecting shaft 20 to slide along the guide structure 1101. The length of the guide structure 1101 can limit the maximum angle of the connecting arm 30, and then limit the opening of the door body 300; when the connecting shaft 20 slides to the locking position 1102 (as shown in Figures 2 and 4), the locking position 1102 locks the position of the connecting shaft 20, limiting the sliding of the connecting shaft 20 along the length direction X of the connecting seat 10, thereby locking the angle of the connecting arm 30 and the connecting seat 10. At this time, the opening of the door body 300 can be kept stable, preventing the door body 300 from changing its opening after a collision, so as to facilitate workers' operations.

[0073] For the convenience of description, the following embodiments are described using a limiting mechanism 100 according to an embodiment of the present application.

[0074] Please refer to Figures 1 to 6. The present application provides a limiting mechanism 100, which includes a connecting seat 10, a connecting shaft 20 and a connecting arm 30. The connecting seat 10 is provided with a guide structure 1101, and the guide structure 1101 is arranged along the length direction X of the connecting seat 10; the connecting shaft 20 slides with the guide structure 1101; the connecting arm 30 is connected to the connecting shaft 20; the connecting seat 10 is also provided with a locking position 1102, and the locking position 1102 is used to lock the position of the connecting shaft 20 in the length direction X of the connecting seat 10.

[0075] It should be noted that the guide structure 1101 can be a structure such as a sliding rod, a sliding rail, a sliding groove or a bar hole. When the guide structure 1101 is a sliding rod, the connecting shaft 20 can be slidingly connected to the sliding rod through a sliding sleeve; when the guide structure 1101 is a sliding rail, the connecting shaft 20 can be slidingly connected to the sliding rail through a slider; when the guide structure 1101 is a sliding groove or a bar hole, the connecting shaft 20 can be slidingly inserted into the sliding groove or the bar hole, and the connecting shaft 20 can also be slidingly matched with the sliding groove or the bar hole through a slider.

[0076] The locking position 1102 can be a latching position adapted to the connecting shaft 20. When the connecting shaft 20 and the connecting base 10 are slidably connected via a slider, the locking position 1102 can also be a latching position that engages with the slider. For example, a latching slot can be provided on the slider, and the locking position 1102 can be a claw or a ball spring that engages the latching slot. There can be one or more locking positions 1102. If there are multiple locking positions 1102, the multiple locking positions 1102 can be arranged along the longitudinal direction X of the connecting base 10. In this way, the connecting arm 30 can be controlled to lock at different deployment angles.

[0077] The connecting base 10 may be connected to the door body 300, and the connecting arm 30 may be connected to the box body 200, or the connecting base 10 may be connected to the box body 200, and the connecting arm 30 may be connected to the door body 300. For example, when the connecting base 10 is fixed to the box body 200, the end of the connecting arm 30 away from the connecting shaft 20 is hinged to the door body 300; when the connecting arm 30 is fixed to the door body 300, the connecting base 10 is hinged to the box body 200. When the door body 300 is closed, the connecting shaft 20 is at one end of the guide structure 1101; when the door body 300 is opened, the connecting shaft 20 slides along the guide structure 1101, and the connecting arm 30 swings outward relative to the connecting base 10, and the connecting arm 30 and the connecting base 10 gradually expand and match the opening of the door body 300; when the connecting shaft 20 reaches the locking position 1102, the locking position 1102 can limit the sliding of the connecting shaft 20 along the guide structure 1101.

[0078] By adopting the sliding cooperation between the connecting shaft 20 and the guide structure 1101, when the connecting arm 30 and the connecting seat 10 are unfolded, the connecting shaft 20 can slide along the guide structure 1101 to adapt to the unfolding angle of the connecting arm 30 and the connecting seat 10; when the connecting shaft 20 slides to the locking position 1102 (the position shown in FIG6 ), the locking position 1102 can lock the position of the connecting shaft 20, so that the position of the connecting shaft 20 along the longitudinal direction X of the connecting seat 10 remains stable, and the unfolding angle of the connecting arm 30 and the connecting seat 10 is locked. In this way, when the connecting seat 10 is fixed to the door body 300 and the connecting arm 30 is connected to the box body 200, the limiting mechanism 100 can limit the opening range of the door body 300, and when the connecting shaft 20 is limited to the locking position 1102, the limiting mechanism 100 can lock the opening of the door body 300 to prevent the movement of the door body 300 from interfering with the worker's work.

[0079] In one embodiment, referring to FIG. 1 , FIG. 4 and FIG. 6 , the guide structure 1101 is a bar-shaped hole.

[0080] The connecting shaft 20 can be fixed to the connecting arm 30 or rotatably mounted on the connecting arm 30. The connecting shaft 20 is slidably inserted into the strip hole. When the angle between the connecting arm 30 and the connecting base 10 changes, the connecting shaft 20 can slide along the strip hole while rotating relative to the connecting arm 30 or the connecting base 10 to avoid interfering with the deployment of the connecting arm 30.

[0081] By adopting the strip hole, the connecting shaft 20 can be guided to slide along the length direction X of the connecting seat 10, and the connecting shaft 20 can be allowed to rotate in the strip hole so as to automatically adapt to the changes in the deployment angle between the connecting arm 30 and the connecting seat 10; the limiting mechanism 100 has a small number of parts, a simple structure, and is easy to process and assemble, which is conducive to reducing the size occupied along the depth direction of the strip hole (such as the Z-axis direction in Figure 5).

[0082] In one embodiment, please refer to Figures 1, 4 and 6, the locking position 1102 is a limiting hole, the limiting hole is connected to the bar hole, and the diameter of the limiting hole is greater than the width of the bar hole; please also refer to Figure 7, the connecting shaft 20 includes a first shaft segment 21 and a second shaft segment 22, the second shaft segment 22 is connected to the first shaft segment 21, the first shaft segment 21 is slidably matched with the bar hole, and the second shaft segment 22 is adapted to the limiting hole to lock the connecting shaft 20.

[0083] The limiting hole can be a circular hole, a rectangular hole, or a regular polygonal hole. The diameter of the limiting hole can be understood as the diameter of the inscribed circle of the limiting hole. Because the diameter of the limiting hole is larger than the width of the strip hole, and the limiting hole and the strip hole are connected, when the first shaft segment 21 slides along the strip hole, the first shaft segment 21 can slide into the limiting hole.

[0084] The second shaft segment 22 is adapted to the limiting hole, which means that the diameter of the second shaft segment 22 is larger than the width of the strip hole, and the diameter of the second shaft segment 22 is smaller than the diameter of the limiting hole. The second shaft segment 22 and the first shaft segment 21 can be but are not limited to being coaxially arranged. When the first shaft segment 21 is in the strip hole, the second shaft segment 22 cannot move into the strip hole along the depth direction of the strip hole; when the first shaft segment 21 is in the limiting hole, the second shaft segment 22 can slide into the limiting hole along the depth direction of the limiting hole; when the second shaft segment 22 enters the limiting hole, since the diameter of the second shaft segment 22 is greater than the width of the strip hole, the second shaft segment 22 cannot slide into the strip hole along the length direction of the strip hole, thereby locking the angle of the connecting arm 30 and the connecting seat 10; after the connecting shaft 20 is reset, the second shaft segment 22 leaves the limiting hole, the first shaft segment 21 enters the limiting hole, and the first shaft segment 21 can slide into the strip hole again, so as to allow the connecting shaft 20 to slide along the guide structure 1101, thereby adjusting the expansion angle of the connecting arm 30 and the connecting seat 10. In particular, the depth direction of the strip hole, the depth direction of the limiting hole, and the axial direction of the connecting shaft 20 can be the same as the height direction Z of the connecting seat 10.

[0085] By cooperating with the limiting second shaft section 22 through the limiting hole, the structure of the locking position 1102 can be simplified. The connecting shaft 20 can be locked and unlocked along the length direction X of the connecting seat 10 by moving along the depth direction of the limiting hole, so that the unlocking and locking of the opening position of the connecting arm 30 are more convenient and the processing of the connecting seat 10 is facilitated.

[0086] In one embodiment, referring to FIG. 4 to FIG. 7 , a third shaft segment 23 is provided at one end of the second shaft segment 22 away from the first shaft segment 21 , and a diameter of the third shaft segment 23 is larger than a diameter of the limiting hole.

[0087] The third shaft segment 23 can be, but is not limited to, a cylindrical, prism, hemispherical or other structure. When the cross section of the third shaft segment 23 is a non-circular structure, the diameter of the third shaft segment 23 refers to the diameter of the circumscribed circle of the cross section of the third shaft segment 23. The third shaft segment 23 can be, but is not limited to, coaxially arranged with the second shaft segment 22.

[0088] The connecting arm 30 can be connected to the end of the first shaft segment 21 away from the second shaft segment 22, or the connecting arm 30 can be connected to the end of the third shaft segment 23 or the second shaft segment 22 away from the first shaft segment 21, and a limiting cap is provided at the end of the first shaft segment 21 away from the second shaft segment 22 to limit the end of the first shaft segment 21 away from the second shaft segment 22 from sliding out of the limiting hole or the strip hole along the depth direction of the strip hole.

[0089] By adopting the third shaft segment 23, when the connecting shaft 20 slides to the second shaft segment 22 and is limited in the limiting hole, since the diameter of the third shaft segment 23 is larger than the diameter of the limiting hole, it can prevent the connecting shaft 20 from sliding out of the limiting hole from the end of the second shaft segment 22 away from the first shaft segment 21, thereby preventing the connecting shaft 20 from separating from the connecting seat 10.

[0090] In one embodiment, referring to FIG. 4 to FIG. 7 , one end of the first shaft segment 21 away from the second shaft segment 22 is connected to the connecting arm 30 .

[0091] The connecting arm 30 can be welded or rotationally connected to the first shaft segment 21. When the connecting arm 30 is rotationally connected to the first shaft segment 21, a limit ring can be provided on the first shaft segment 21 to limit the connecting arm 30 from sliding along the axial direction on the first shaft segment 21.

[0092] Referring to Figure 5, the end of the first shaft segment 21 away from the second shaft segment 22 is connected to the connecting arm 30, and the connecting arm 30 can limit the upward movement of the connecting shaft 20, that is, limit the movement of the connecting shaft 20 toward the side of the connecting seat 10 away from the connecting arm 30, and can prevent the connecting shaft 20 from sliding out of the limiting hole or the strip hole from the end of the first shaft segment 21 away from the second shaft segment 22, thereby preventing the connecting shaft 20 from separating from the connecting seat 10.

[0093] In one embodiment, referring to Figures 4 to 7, a positioning plate 24 is provided in the middle of the axial direction of the first shaft segment 21 (the Z-axis direction in Figure 7), and the positioning plate 24 is used to stop and position the connecting arm 30. The connecting arm 30 is sleeved on the first shaft segment 21, and the connecting arm 30 is located on the side of the positioning plate 24 away from the second shaft segment 22.

[0094] The positioning plate 24 can be, but is not limited to, integrally formed with the first shaft segment 21. The positioning plate 24 can be circular, square, or other shapes, and its area can be larger than the cross-sectional area of ​​the first shaft segment 21. The axial direction of the first shaft segment 21 is the same as the depth direction of the limiting hole.

[0095] A first through-hole is defined on the connecting arm 30 at a position corresponding to the first shaft segment 21. The first shaft segment 21 fits snugly into the first through-hole. The positioning plate 24, which has an area larger than the cross-sectional area of ​​the first through-hole, acts as a stop for the connecting arm 30, restricting its movement toward the end of the first shaft segment 21 closest to the second shaft segment 22. After the first shaft segment 21 is inserted into the first through-hole, the first shaft segment 21 and the connecting arm 30 can be secured together by, but is not limited to, welding.

[0096] By stopping the connecting arm 30 through the positioning plate 24, the position of the connecting arm 30 on the first shaft segment 21 can be positioned, the distance between the connecting arm 30 and the third shaft segment 23 can be controlled, and the sliding range of the connecting shaft 20 along the depth direction of the strip hole can be limited.

[0097] In one embodiment, referring to Figures 4 to 7, the connecting seat 10 includes a connecting plate 11, a first side plate 12 and a second side plate 13. The first side plate 12 is arranged on one side of the connecting plate 11 along the width direction (such as the Y-axis direction in Figure 5), and the second side plate 13 is arranged on the other side of the connecting plate 11 along the width direction. The first side plate 12 and the second side plate 13 are located on one side of the connecting plate 11 along the thickness direction (such as the Z-axis direction in Figure 5), and the guide structure 1101 and the locking position 1102 are arranged on the connecting plate 11.

[0098] The first side panel 12 and the second side panel 13 can be formed by bending the side edges of the connecting plate 11, but are not limited to bending the entire plate, which facilitates the processing of the connecting base 10. The cross section of the connecting base 10 can be U-shaped, and the strip hole can be located in the middle of the width direction of the connecting plate 11.

[0099] By arranging the first side plate 12 and the second side plate 13 on the sides of the connecting plate 11 , the bending strength of the connecting seat 10 can be enhanced, thereby preventing the connecting seat 10 from bending and deforming.

[0100] In one embodiment, referring to FIG. 4 to FIG. 7 , the connecting base 10 further includes a fixing member 14 , and the fixing member 14 connects the first side plate 12 and the second side plate 13 .

[0101] The fixing member 14 may be a plate, a screw, a rivet, a pin, etc. The fixing member 14 and the first side plate 12 or the second side plate 13 may be connected and fixed by threaded connection, riveting, welding, etc.

[0102] Optionally, the fixing member 14 is a pin. A second through-hole is formed on the first side panel 12, and a third through-hole is formed on the second side panel 13 opposite the second through-hole. The ends of the fixing member 14 are inserted into the second through-hole and the third through-hole, respectively. The fixing member 14 can be plug-welded to the first and second side panels 12 and 13. After welding, the ends of the pin are smoothed to improve the appearance.

[0103] By connecting the first side panel 12 and the second side panel 13 with the fixing member 14 , the distance between the first side panel 12 and the second side panel 13 can be kept stable, thereby enhancing the stability of the first side panel 12 and the second side panel 13 .

[0104] In one embodiment, referring to FIG. 4 to FIG. 7 , there are multiple fixing members 14 , and the multiple fixing members 14 are arranged along the length direction of the connecting plate 11 (eg, the X-axis direction in FIG. 4 ).

[0105] The multiple fixing members 14 can all be pins, and using the same fixing members 14 facilitates assembly. The multiple fixing members 14 can be, but are not limited to, arranged at equal intervals. Arranging them at equal intervals allows for evenly distributed connection points between the first side panel 12 and the second side panel 13. Of course, in other embodiments, the multiple fixing members 14 can also have different structures, such as some fixing members 14 being plates and some being pins.

[0106] By adopting a plurality of fixing members 14 , the stability of the connection between the first side plate 12 and the second side plate 13 can be improved, and the structural strength of the connecting base 10 can be enhanced.

[0107] In one embodiment, referring to FIG. 2 to FIG. 5 , a fastener 15 for connecting with the door body 300 is installed on the first side panel 12 .

[0108] The fasteners 15 may be rivets, bolts, or pins, etc. There may be multiple fasteners 15 , and the multiple fasteners 15 may be arranged along the length direction of the first side panel 12 , so that when the first side panel 12 is connected to the box body 200 , the stability of the connection portion is improved.

[0109] The first side panel 12 can be connected and fixed to the door body 300 by the fastener 15 , and the connecting base 10 can be installed on the door body 300 .

[0110] In one embodiment, referring to FIG. 4 to FIG. 7 , the connecting arm 30 is located on the other side of the connecting plate 11 along the thickness direction.

[0111] That is, the connecting arm 30 is located on the side of the connecting plate 11 away from the first side plate 12 and the second side plate 13. Specifically, the third shaft segment 23 is located at the end of the connecting shaft 20 close to the first side plate 12 and the second side plate 13, and the first shaft segment 21 is located at the end of the connecting shaft 20 away from the first side plate 12 and the second side plate 13.

[0112] By setting the connecting arm 30 on the side of the connecting plate 11 away from the first side plate 12 and the second side plate 13, the first side plate 12 and the second side plate 13 can be prevented from interfering with the movement of the connecting arm 30, which is beneficial to reducing the distance between the connecting arm 30 and the connecting plate 11, reducing the length of the connecting shaft 20, and improving the stability between the connecting arm 30 and the connecting seat 10.

[0113] In one embodiment, referring to FIG. 4 to FIG. 7 , a reinforcing rib 34 is provided on the connecting arm 30 . The reinforcing rib 34 is provided along the length direction S of the connecting arm 30 .

[0114] The reinforcing rib 34 may be, but is not limited to, located in the middle of the width direction of the connecting arm 30. The number of reinforcing ribs 34 may be one or more. When there are multiple reinforcing ribs 34, the reinforcing ribs 34 may be respectively provided on opposite sides of the connecting arm 30. The width direction of the connecting arm 30 may be perpendicular to the axial direction of the connecting shaft 20 and the length direction S of the connecting arm 30.

[0115] By providing the reinforcing rib 34 , the bending strength of the connecting arm 30 can be enhanced, thereby preventing the connecting arm 30 from bending and deforming to affect the opening and closing of the door body 300 .

[0116] In one embodiment, referring to Figures 4 to 7, the connecting arm 30 includes a first plate segment 31, a second plate segment 32 and a third plate segment 33. The first plate segment 31 is connected to the connecting shaft 20, the second plate segment 32 is connected to the end of the first plate segment 31 away from the connecting shaft 20, and the third plate segment 33 is connected to the end of the second plate segment 32 away from the first plate segment 31. The second plate segment 32 is inclined toward a direction away from the connecting seat 10 from the end of the first plate segment 31 away from the connecting shaft 20 to the end of the third plate segment 33 close to the connecting shaft 20.

[0117] The first plate segment 31 may be perpendicular to the connecting axis 20, and the length direction of the third plate segment 33 may be parallel to the length direction of the first plate segment 31 (such as the S direction in FIG. 4 ). The length of the first plate segment 31 may be smaller than that of the second plate segment 32, and the length of the first plate segment 31 may also be smaller than that of the third plate segment 33. The second plate segment 32 is inclined in a direction away from the connecting plate 11 from the end of the first plate segment 31 away from the connecting axis 20 to the end of the third plate segment 33 closer to the connecting axis 20. That is, when the first plate segment 31 is parallel to the connecting plate 11, the distance between the end of the second plate segment 32 away from the first plate segment 31 and the connecting plate 11 (along the axis of the connecting axis 20) is greater than the distance between the end of the second plate segment 32 closer to the first plate segment 31 and the connecting plate 11. This makes the transition between the second plate segment 32 and the first plate segment 31 and the third plate segment 33 smoother, and makes the third plate segment 33 farther away from the connecting plate 11 than the first plate segment 31.

[0118] By adopting the first plate segment 31, the second plate segment 32 and the third plate segment 33, when the connecting arm 30 is folded to the side of the connecting seat 10 (as shown in Figures 2 and 4), the distance between the second plate segment 32 and the third plate segment 33 and the connecting seat 10 is larger, which helps to avoid friction between the end of the connecting arm 30 away from the connecting shaft 20 and the connecting seat 10.

[0119] In one embodiment, referring to FIG. 4 to FIG. 7 , the reinforcing rib 34 is located on a side of the third plate segment 33 close to the connecting seat 10 , and the reinforcing rib 34 is connected to the second plate segment 32 and the third plate segment 33 .

[0120] The height of the reinforcing rib 34 may gradually decrease from one end close to the first plate segment 31 to one end away from the first plate segment 31 , so as to reduce friction between the reinforcing rib 34 and the connecting plate 11 .

[0121] The second plate segment 32 and the third plate segment 33 are connected by the reinforcing rib 34, which can improve the structural strength of the second plate segment 32 and the third plate segment 33, prevent the second plate segment 32 and the third plate segment 33 from bending and deformation, and keep the angle between the third plate segment 33 and the second plate segment 32 stable.

[0122] In one embodiment, referring to Figures 4 to 7 , the side surfaces of the reinforcing rib 34 in the width direction are inclined from the side of the reinforcing rib 34 close to the third plate segment 33 to the side of the reinforcing rib 34 away from the third plate segment 33 toward the middle of the width direction of the reinforcing rib 34. The width direction of the reinforcing rib 34 is the same as the width direction of the third plate segment 33.

[0123] Referring to Figure 6 , the side surfaces of the rib 34 in the width direction refer to the side surfaces on the left and right sides of the rib 34. The side surfaces of the rib 34 in the width direction are inclined from the third plate segment 33 toward the middle of the rib 34 in the width direction. The width of the rib 34 gradually decreases from the side close to the third plate segment 33 to the side away from the third plate segment 33. Optionally, the angle between the side surfaces in the width direction of the rib 34 and the height direction of the rib 34 can be 1°-30°, for example, 5°, 10°, or 15°. The angles between the two side surfaces in the width direction of the rib 34 and the height direction of the rib 34 can be equal. The height direction of the rib 34 is the same as the thickness direction of the third plate segment 33.

[0124] The two side surfaces in the width direction of the reinforcing rib 34 are inclined to form a certain draft angle, which facilitates demoulding during casting.

[0125] In one embodiment, referring to FIG. 4 to FIG. 7 , a rotating shaft 36 is installed at one end of the connecting arm 30 away from the connecting shaft 20 , and the rotating shaft 36 is used for being hinged to the box body 200 .

[0126] That is, one end of the third plate segment 33 away from the first plate segment 31 is hinged to the box body 200 via the rotation shaft 36 , and the rotation shaft 36 can rotate relative to the third plate segment 33 or the box body 200 .

[0127] By adopting the rotating shaft 36 , the connecting arm 30 can be hinged to the box body 200 , so that when the door body 300 rotates, the connecting arm 30 can rotate relative to the box body 200 to adapt to the opening of the door body 300 .

[0128] In one embodiment, referring to FIG. 4 to FIG. 7 , a shaft sleeve 35 is sleeved on the rotating shaft 36 , and the connecting arm 30 is slidably sleeved on the shaft sleeve 35 .

[0129] A fourth through-hole is formed at one end of the third plate segment 33 away from the connecting shaft 20, into which a sleeve 35 is slidably inserted. When the connecting shaft 20 moves along the Z-axis, the third plate segment 33 can slide along the sleeve 35 so that the height of the connecting arm 30 and the connecting shaft 20 remain aligned.

[0130] The rotating shaft 36 can be a screw or a pin, and the upper end surface of the sleeve 35 is higher than the upper surface of the third plate segment 33 , so that when the rotating shaft 36 is connected to the box body 200 , the rotating shaft 36 will not press on the third plate segment 33 .

[0131] The sleeve 35 is slidably connected to the connecting arm 30 , so that the connecting arm 30 can slide along the sleeve 35 , thereby facilitating the connecting shaft 20 to slide along the depth direction of the limiting hole.

[0132] In one embodiment, referring to Figures 4 to 7, the end of the sleeve 35 close to the connecting seat 10 protrudes from the side of the connecting arm 30 close to the connecting seat 10; and / or, the end of the sleeve 35 away from the connecting seat 10 protrudes from the side of the connecting arm 30 away from the connecting seat 10.

[0133] Referring to Figure 5 , the end of the sleeve 35 closest to the connection base 10 is the upper end of the sleeve 35 , which is higher than the upper surface of the third plate segment 33 . The end of the sleeve 35 away from the connection base 10 is the lower end of the sleeve 35 , which is lower than the lower surface of the third plate segment 33 .

[0134] The third plate segment 33 has a mounting hole formed therein, through which a sleeve 35 is inserted, with both ends of the sleeve 35 extending out of the mounting hole. Flanged flanges can be provided at both ends of the sleeve 35 extending out of the mounting hole to facilitate securing the sleeve 35 to the third plate segment 33 and prevent the sleeve 35 from falling out of the mounting hole.

[0135] By having the upper end of the sleeve 35 protrude from the upper surface of the connecting seat 10, the upper surface of the third plate segment 33 can be prevented from contacting the rotating shaft 36, thereby hindering the rotation of the connecting arm 30; by having the lower end of the sleeve 35 protrude from the lower surface of the connecting seat 10, the lower surface of the third plate segment 33 can be prevented from contacting the box body 200, thereby hindering the rotation of the connecting arm 30.

[0136] On the second aspect, please refer to Figures 1 to 3. The embodiment of the present application also provides an energy storage device, including a box body 200 and a door body 300 hingedly installed on the box body 200, and also includes the limiting mechanism 100 in any of the above embodiments, the connecting seat 10 is connected to the door body 300, and the connecting arm 30 is connected to the box body 200; or, the connecting seat 10 is connected to the box body 200, and the connecting arm 30 is connected to the door body 300.

[0137] The energy storage device may be, but is not limited to, an electrical cabinet, an energy storage container, etc. One or more batteries may also be installed in the box 200. When there are multiple batteries in the box 200, the multiple batteries may be connected in series, in parallel, or in mixed connection.

[0138] Please refer to Figures 4 and 6. The locking position 1102 is located at one end of the strip hole close to the hinged portion of the door body 300. When the door body 300 is closed, the connecting shaft 20 is located at one end of the strip hole away from the hinged portion of the door body 300. When the connecting seat 10 is connected to the door body 300 and the connecting arm 30 is connected to the box body 200, when the door body 300 is opened, the connecting seat 10 swings outward with the door body 300, and the connecting shaft 20 slides toward the hinged portion of the door body 300. When the connecting shaft 20 slides into the limiting hole, the second shaft segment 22 falls into the limiting hole, and the limiting hole and the second shaft segment 22 are locked. The second shaft segment 22 cooperates to lock the position of the connecting shaft 20, so that the opening of the door body 300 and the box body 200 are locked; when the connecting seat 10 is connected to the box body 200, the connecting arm 30 is connected to the door body 300, and when the door body 300 is opened, the connecting arm 30 swings outward with the door body 300, and the connecting shaft 20 slides toward the hinge part of the box body 200; when the connecting shaft 20 slides into the limiting hole, the second shaft segment 22 falls into the limiting hole, and the limiting hole cooperates with the second shaft segment 22 to lock the position of the connecting shaft 20, so that the opening of the door body 300 and the box body 200 are locked.

[0139] By adopting the limiting mechanism 100 in the above embodiment, when the door body 300 is opened, the door body 300 drives the connecting seat 10 to swing, and the connecting arm 30 drives the connecting shaft 20 to slide along the guide structure 1101. The sliding stroke of the connecting shaft 20 along the guide structure 1101 can control the opening of the door body 300; when the connecting shaft 20 is locked in the locking position 1102, the position of the connecting arm 30 and the connecting seat 10 remains fixed, so that the opening of the door body 300 is locked to facilitate the workers' operation.

[0140] Referring to Figures 1 to 7, an embodiment of the present application provides an energy storage device, which includes a housing 200, a door 300, and a limiting mechanism 100. A connecting seat 10 is riveted to the door 300, and a connecting arm 30 is hinged to the housing 200, with the connecting arm 30 being located on the lower side of the connecting seat 10. When the door 300 is closed, the connecting shaft 20 slides to the end of the strip hole away from the limiting hole; when the door 300 is opened, the connecting shaft 20 gradually slides to the limiting hole; after the first shaft section 21 of the connecting shaft 20 slides into the limiting hole, the connecting arm 30 and the connecting shaft 20 fall under the action of gravity, and the second shaft section 22 slides into the limiting hole. The limiting hole locks the position of the connecting shaft 20, thereby locking the opening of the door 300. When the door body 300 needs to be closed, the connecting arm 30 is pulled upward, and the connecting arm 30 drives the connecting shaft 20 to move upward, and the first shaft section 21 enters the limiting hole. At this time, the door body 300 is pushed, and the first shaft section 21 slides into the strip hole and slides along the strip hole to close the door body 300.

[0141] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
