Description

Door assembly and electrical equipment

Technical Field

Embodiments of the present disclosure relate generally to the field of door apparatuses, and more particularly, to a door assembly and an electrical apparatus including the same.

Background

The door bodies of existing electrical apparatuses (e.g. electrical cabinets or switch cabinets) are usually opened in a pivoting manner with respect to the frame (e.g. cabinet) of the apparatus. In the occasion that the space outside electrical equipment is narrow, such an opening mode often leads to the door body can't normally open to influence the normal use of equipment. For example, in a vehicle such as a ship, the installation space of a power distribution cabinet or a switch cabinet is limited, and the cabinet door cannot be completely opened. One existing solution is to detach the door from the cabinet. Such a manner brings about a certain potential safety hazard.

SUMMERY OF THE UTILITY MODEL

Embodiments of the present disclosure provide a door assembly and an electrical apparatus including the same to at least partially solve the above-mentioned problems occurring in the prior art.

In one aspect of the present disclosure, a door assembly is provided. The door assembly includes a door body and a connecting member. The door body is adapted to selectively close the opening of the frame. The connecting member includes: the first connecting part is pivotally connected to the door body, so that the connecting part is suitable for pivoting relative to the door body in a plane perpendicular to the plane of the opening; and a second connecting portion pivotally and slidably connected to the frame such that the connecting member is adapted to pivot in a plane relative to the frame and slide to a first position inside the opening or a second position outside the opening. When the connecting part slides to the first position, the door body is suitable for closing the opening; when the connecting part slides to the second position, the door body is suitable for being moved to an opening position through the pivoting of the connecting part, and in the opening position, the plane of the door body is parallel to the plane of the opening.

In this context, "pivotally connected" includes both the case where two members are directly connected to each other and the case where two members are indirectly connected to each other through the other member or members. For example, the phrase "the first connecting portion is pivotally connected to the door body" includes both a case where the first connecting portion is directly connected to the door body and a case where one or more other members are provided between the first connecting portion and the door body so that the first connecting portion can pivot with respect to the door body.

In this way, the door body is movably connected to the frame by means of the connecting part, so that it can be switched between the closed position and the open position. During opening, the door body is no longer pivotally movable about an axis relative to the frame, but moves outwardly relative to the opening in a manner substantially parallel to the plane of the opening. Thereafter, the door body can also be moved to one side to the open position by means of a pivoting movement of the connecting member relative to the door body and the frame. In the opening position, the plane of the door body and the plane of the opening can be in a basically parallel state. The door body opening mode enables the space required by the door body during opening to be small, so that the door assembly is suitable for being applied to occasions with narrow space.

In some embodiments, the connecting member may be elongate in shape extending along the longitudinal axis. The first connecting portion may include a connecting hole at one end of the connecting member, through which the connecting member may be pivotally connected to the door body, and the second connecting portion may include a groove extending along the longitudinal axis. The door assembly may further include a positioning post secured to the perimeter of the opening. At least a portion of the positioning post extends into the slot such that the connecting part is adapted to pivot and slide relative to the positioning post. In this way, the connecting part achieves a pivotal connection with the door body and a pivotal and slidable connection with the positioning post through the connecting hole and the groove. The structure of the connection mode is simple, the reliability is high, and therefore the door assembly is convenient to realize and apply.

In some embodiments, the connecting member may be tubular and may include a rectangular cross-sectional shape. The slots may comprise through slots in two oppositely disposed walls of the connection part, respectively, and the positioning posts pass through both slots. The tubular connecting member contributes to weight saving and material saving of the connecting member while ensuring the required strength and rigidity of the connecting member. The positioning column penetrates through the two grooves, so that the connection between the connecting part and the positioning column is more reliable.

In some embodiments, the door assembly may further include a fixing bracket fixed to a periphery of the opening. The fixing bracket may include a flat surface adapted to engage with the connection member such that the connection member can pivot and slide in a state of being engaged with the flat surface. The positioning column can be fixed on the fixing support. In this way, the positioning post can be firmly fixed to the frame by the fixing bracket. Furthermore, the connecting member can always be in contact with the flat surface of the fixing bracket during pivoting and sliding with respect to the frame. The flat surface provides support and guidance for the connecting member, thereby making the movement of the connecting member smoother and more stable.

In some embodiments, the door assembly may further include a support bar. The support bar may extend in a first direction parallel to the plane of the opening. The first connecting portion may be pivotally connected to the support bar. The door assembly may further include a slider. The slider is set up on the door body. The sliding block is suitable for sliding on the supporting rod, so that the door body can slide along the first direction relative to the supporting rod. In this way, the door body can slide on the support rod through the slide block. Therefore, during opening, the door body can not only at least partially open the opening by means of pivoting of the connecting member, but can also further slide along the support rod to one side of the opening, thereby making the range in which the opening is opened larger.

In some embodiments, the door body may further be provided with a hook. The hook is adapted to be connected to the hook fixture in a state where the door body slides in the first direction to the open position. Under the condition that the door body slides to a position close to one end of the supporting rod through the sliding block (namely, under the condition that the door body slides to an opening position), one part of the door body can be supported on the supporting rod through the sliding block, and the other part of the door body can be supported on the hook fixing piece through the hook. The hook fastener may be, for example, a locating post or rod projecting outwardly from the surface of the frame. In this way, the door body can be stably supported in a state of sliding to the open position, thereby preventing the door body from twisting or falling off relative to the support rod.

In some embodiments, the door assembly may include a support rod. One connecting member is provided at each of two different positions on the support bar (e.g., positions near both ends of the support bar, respectively). In this way, the door body can be reliably attached to the frame.

In some embodiments, the door assembly may include two support bars. The two support bars may be spaced apart in a second direction parallel to the plane of the opening and perpendicular to the first direction (e.g., the two support bars may be spaced apart one above the other). Two connecting parts are respectively arranged at two different positions on each supporting rod. The connection mode provides more connection points for the door body, so that the door body can be connected to the frame more reliably.

In another aspect of the present disclosure, an electrical device is provided. The electrical device includes the door assembly according to the above aspect. Since the electrical appliance includes the door assembly as described above, the same advantageous effects as those of the door assembly can be provided.

In some embodiments, the electrical device may comprise a power distribution cabinet or a switchgear cabinet. With the adoption of the mode, the cabinet door of the power distribution cabinet or the switch cabinet can be still conveniently opened under the situation that the power distribution cabinet or the switch cabinet is installed in a narrow space, so that the convenience of operation is improved.

It should be understood that this summary is not intended to identify key or critical features of the embodiments of the disclosure, nor is it intended to be used to limit the scope of the disclosure. Other features of the present disclosure will become apparent from the following description.

Detailed Description

The principles of the present disclosure will now be described with reference to various exemplary embodiments shown in the drawings. It should be understood that these examples are described merely to enable those skilled in the art to better understand and further implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way. It should be noted that where feasible, similar or identical reference numerals may be used in the figures and that similar or identical reference numerals may indicate similar or identical functions. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the disclosure described herein.

As has been briefly described above, the present disclosure is directed to providing a door assembly that requires a relatively small space for the door body during opening thereof. Generally, the door body of the door assembly according to the embodiment of the present disclosure can move outward relative to the opening in a manner substantially parallel to the plane of the opening, and thus achieve full opening. Compared with the prior art that the door body is opened by pivoting, the mode that the door body moves parallel to the plane of the opening can greatly save the space required by opening the door. Accordingly, the door assembly and the electrical device according to the embodiments of the present disclosure can at least partially solve the above-mentioned problems in the existing door assembly. Some exemplary embodiments of door assemblies and electrical devices according to the present disclosure are now described with reference to fig. 1-5.

As shown in fig. 1, an electrical appliance 1 according to an embodiment of the present disclosure includes a door assembly 10. In some embodiments, the electrical apparatus 1 may comprise a switch cabinet or the like, and the frame F may comprise a cabinet body of the switch cabinet or the switch cabinet. An opening C is provided in the frame F. The operator can access the inside of the electrical apparatus 1 through the opening C, or operate the operable components inside the electrical apparatus 1 through the opening C.

The door assembly 10 includes a door body 20. The door 20 may selectively close the opening C of the frame F as needed. The door assembly 10 also includes a connecting member 40. The door body 20 is movably connected to the frame F of the electric apparatus 1 by a connection member 40.

Specifically, for example, referring to fig. 3 and 5, the connection member 40 includes a first connection portion 41. The connection member 40 is pivotally connected to the door body 20 by a first connection portion 41 such that the connection member 40 can pivot relative to the door body 20 in a plane B (see fig. 2 and 3) perpendicular to the plane of the opening C. It should be understood that the first connection portion 41 may be implemented in various pivotal connection structures in different embodiments. Hereinafter, the structure of the first connection portion 41 will be described in detail.

Referring to fig. 2 and 3, the connection member 40 further includes a second connection portion 42. The second connecting portion 42 is pivotally and slidably connected to the frame F. That is, the second connecting portion 42 actually constitutes a sliding pair and a revolute pair connection between the connecting member 40 and the frame F. By means of the second connection 42, the connecting member 40 can pivot in the plane B with respect to the frame F on the one hand and can slide in the plane B with respect to the frame F on the other hand. It should also be appreciated that the above described linkage of the sliding pair and the revolute pair may be implemented in a variety of configurations in different embodiments. Hereinafter, the connection structure of the second connection portion 42 and the frame F will be described in detail.

As shown in fig. 2, the connecting member 40 is slidable to a position substantially inside the opening C (also referred to herein as a "first position"). When the connection member 40 is located at the first position, the door body 20 is located at the closing position, thereby closing the opening C. Further, as shown in fig. 3, the connecting member 40 is also slidable to a position substantially outside the opening C (also referred to herein as a "second position"). When the connection member 40 is located at the second position, the door body 20 can be pivoted relative to the connection member 40 by the first connection portion 41, and the connection member 40 can be pivoted relative to the frame F by the second connection portion 42, so that the door body 20 can be moved to the opening position to the side of the opening C by the above-described two pivoting movements. In the open position, the plane of the door 20 is substantially parallel to the plane of the opening C.

In some embodiments, the door 20 remains substantially parallel to the plane of the opening C during the movement from the closed position to the open position. However, it should be understood that, since the second connecting portion 42 actually constitutes a moving pair and a rotating pair connection between the connecting member 40 and the frame F, and the door body 20 can pivot relative to the connecting member 40, in other embodiments, the door body 20 may also be at an angle relative to the plane of the opening C during the process that the door body 20 is moved from the closed position to the open position, and after finally being moved to the open position, the door body 20 assumes a state substantially parallel to the plane of the opening C.

When the door body 20 is in the open position, there is a gap between the door body 20 and the frame F, i.e., at least a portion of the opening C can be opened. The operator can access the inside of the electrical apparatus 1 through the opened portion of the opening C, or operate the operable components inside the electrical apparatus 1 through the opened portion.

It can be seen that the door body 20 of the door assembly 10 according to the embodiment of the present disclosure can substantially maintain a state parallel to the plane of the opening C during the opening process, and the opening of the door is achieved by the movement of the door body 20 to one side of the opening C. Therefore, the door assembly 10 according to the embodiment of the present disclosure can greatly save the space required for opening the door body 20, compared to the conventional manner in which the door body pivotally moves about an axis with respect to the frame (in which at least one sector space having a radius equal to the width of the door body, for example, a sector space of 90 degrees, is required).

As described above, the connection member 40 may be implemented in various ways in different embodiments. Several example embodiments will be described below. However, it should be understood that the following exemplary descriptions of specific forms of the connection member 40 (including the first connection portion 41 and the second connection portion 42) in the following embodiments do not constitute limitations on the composition and structure of the connection member 40. Other types and configurations of connecting members 40 may also be suitable for use with the door assembly 10 according to embodiments of the present disclosure.

In some embodiments, for example, referring to fig. 3 and 5, the connecting member 40 may be an elongated shape, e.g., a rod, or a tube, extending along the longitudinal axis a. The first connection part 41 may include a connection hole 43 at one end of the connection part 40. The connection member 40 may be pivotally connected to the door body 20 through a connection hole 43. Alternatively, in other embodiments, the first connection portion 41 may include a pivot shaft or pin (not shown) projecting outwardly from the connection member 40. Accordingly, the door body 20 may include a connection hole (not shown). The pivot shaft or pivot pin is pivotally connected to the attachment hole.

In some embodiments, for example, referring to fig. 2-5, the second connection portion 42 may include a slot 44 extending along the longitudinal axis a. Accordingly, the door assembly 10 may further include a positioning post 50 fixed to the periphery of the opening C of the frame F. At least a portion of the positioning post 50 extends into the groove 44, so that the above-mentioned connection structure of the moving pair and the rotating pair is realized between the groove 44 of the connection part 40 and the positioning post 50.

Alternatively, in some other embodiments, the second connection portion 42 may include a positioning post (not shown) protruding outward from the connection portion 40. Accordingly, the door assembly 10 may include a positioning groove (not shown) provided at the periphery of the opening C of the frame F. The positioning posts of the connecting member 40 protrude into positioning grooves in the periphery of the opening C of the frame F, and can pivot and slide relative to the positioning grooves.

In still other embodiments, the door assembly 10 may further include a sleeve (not shown) disposed about the opening C of the frame F and pivotable relative to the frame F. Accordingly, the second connecting portion 42 is configured as a portion of the elongated connecting member 40 that is inserted into the sleeve. In this way, the second connection portion 42 of the connection member 40 can slide within the sleeve, and the connection member 40 can pivot with the sleeve relative to the frame F.

The various connecting members 40 described above are simple to implement and reliable, thereby facilitating implementation and application of the door assembly.

Referring again to fig. 2-5, in some embodiments, the connecting member 40 may be tubular and include a rectangular cross-sectional shape. In such an embodiment, the connecting member 40 may include two walls 45, 46 (see fig. 4 and 5) disposed opposite one another. The slot 44 may include two slots 44 therethrough on walls 45, 46, respectively. The positioning posts 50 pass through the two slots 44.

The tubular connecting member 40 contributes to weight saving of the connecting member 40 and saving of manufacturing material while ensuring required strength and rigidity of the connecting member 40. The positioning posts 50 pass through the two slots 44, so that the connection between the connecting part 40 and the positioning posts 50 is more reliable.

In some embodiments, for example, referring to fig. 2-4, the door assembly 10 may further include a fixing bracket 51 fixed to the periphery of the opening C. The fixed bracket 51 may be in the form of a frame and may include a flat surface 52. The fixed bracket 51 may also include an aperture 53. The positioning post 50 can be inserted through and fixed in the hole 53. The positioning posts 50 can pass through the slots 44 and ultimately out of the bottom surface of the connecting part 40. A nut 54 may be tightened on the portion of the positioning post 50 that extends out from the bottom surface of the attachment member 40 to prevent the positioning post 50 from being removed from the slot 44. With the above-described structure, the surface 52 can be always in contact with the corresponding surface of the link member 40 during the pivoting and sliding of the link member 40 with respect to the frame F. The surface 52 provides support and guidance for the connecting member 40 so that movement of the connecting member 40 is smoother and more stable.

Referring to fig. 1-3, in some embodiments, the door assembly 10 may further include a support bar 30. The support bar 30 is parallel to a plane in which the opening C is located, and extends in a direction X (also referred to herein as a "first direction") in fig. 1 to 3. It should be understood that although in the embodiment shown in fig. 1, the first direction X is a substantially horizontal direction, the present disclosure is not particularly limited in this regard. The first direction X may be any direction parallel to the plane of the opening C, as long as the door body 20 moves to the side of the opening C along the direction, and at least a portion of the opening C is finally opened.

With continued reference to fig. 1-3, the first connection portion 41 (e.g., the connection hole 43) may be pivotally connected to the support bar 30, which in turn connects the support bar 30 to the door body 20. Such a connection mode is a case where the first connection portion 41 is indirectly and pivotally connected to the door body 20.

The door assembly 10 may also include a slider 60. The slider 60 is provided on the door body 20. In this way, the door body 20 can slide relative to the support bar 30 by the slider 60. For example, in the embodiment shown in fig. 2 and 3, in the closed position of the door body 20 (see fig. 2), the slider 60 is located at a position close to the one end 31 of the support bar 30; during the opening of the door 20, the door 20 can slide in the first direction to a position close to the other end 32 of the support bar 30 by the slider 60. The opening C is opened to a greater extent by sliding the door body 20 on the support bar 30, thereby facilitating the operator to enter the interior of the electrical apparatus 1 or operate the operable components inside the electrical apparatus 1.

In some embodiments, for example, referring to fig. 2 and 3, the door body 20 may be provided with a hook 70 on a side thereof facing the opening C. The hook 70 may be hooked on a hook fixture (not shown, for example, may be provided at an appropriate position on the surface of the electrical appliance 1) in a state where the door body 20 is slid to a position near the other end 32 of the support bar 30 by the slider 60. The hook fixture may be, for example, a locating post or rod projecting outwardly from the surface of the electrical apparatus 1. In this way, the door body 20 can be stably supported in a state of being slid to the open position, thereby preventing the door body 20 from being twisted or falling off with respect to the support bar 30.

Further, the door assembly 10 according to the embodiment of the present disclosure may be provided with a suitable number of support bars 30 as needed. In some embodiments, for example, referring to fig. 2, the door assembly 10 may include a support bar 30. At two different positions on the support bar 30, for example, near the ends 31 and 32, respectively, there is provided one connecting member 40 each.

Alternatively or additionally, for example, referring to fig. 3, in other embodiments, the door assembly 10 may include two support bars 30. The two support rods 30 may be spaced apart from each other. For example, in the embodiment shown in fig. 3, the two support rods 30 may be disposed at intervals from each other in a direction Y (also referred to herein as a "second direction", e.g., a vertical direction) perpendicular to the first direction X (e.g., a horizontal direction). In such an embodiment, one connecting member 40 is provided at each of two different locations on each support rod 30, for example, near ends 31 and 32, respectively.

Such a coupling manner provides more coupling points for the door body 20, so that the door body 20 can be more reliably coupled to the frame F.

Based on the above description, the door assembly 10 according to the embodiment of the present disclosure can move outward with respect to the opening C in a manner substantially parallel to the plane of the opening C. In the open position, the door 20 may be substantially parallel to the plane of the opening C. The door 20 is opened in such a manner that the door 20 requires a small space during opening, so that the door assembly 10 is suitable for use in a narrow space.

Therefore, the electrical apparatus 1 (e.g., a power distribution cabinet or a switch cabinet) including the door assembly 10 according to the embodiment of the present disclosure has a particular advantage in a place where an installation space on a vehicle such as a ship is limited.

It is to be understood that the above detailed embodiments of the disclosure are merely illustrative of or explaining the principles of the disclosure and are not limiting of the disclosure. Therefore, any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Also, it is intended that the following claims cover all such changes and modifications that fall within the scope and boundaries of the claims or the equivalents of the scope and boundaries.
