Description

Electric switchgear

[0001] The present invention relates to an electric switching device, and more specifically, to an electric switching device having a structure that enables easy remote opening and closing operations while ensuring safety.

[0002] A load interrupter switch (LIS) is a device designed to protect substation equipment by opening, closing, or interrupting load current. A load interrupter switch is configured to perform the above-described tasks through an opening and closing operation.

[0003] Traditional load switches are manually operated by operators. In the event of an accident, operators typically manually open and close the load switch by directly manipulating the opening / closing handle.

[0004] To facilitate manual opening and closing, a load switch structured to reduce the amount of force required by utilizing elastic members such as springs or link members has been introduced. However, load switches with the above structures are also operated by force applied by the operator, i.e., are provided in a manual form.

[0005] In the case of manual load switches, the opening and closing operation is performed by the operator's judgment and manipulation. Furthermore, the operator also determines whether the operation has been completed completely. Therefore, the operator's subjective judgment must be involved, which can lead to inaccurate results.

[0006] Furthermore, panels where load switches are connected typically carry high voltages. Therefore, in the event of an unexpected accident, there is a risk of injury to workers near the panel operating the load switches.

[0007] Therefore, there is a need for a load switch that can be operated remotely while improving the accuracy of operation.

[0008] Korean Patent No. 10-1059585 discloses a load-disconnecting device. Specifically, the device includes a manual load disconnector with an electronic arc extinguishing function that manually interrupts DC current using a plug contact.

[0009] However, the load-disconnecting device disclosed in the above-mentioned prior art document only provides a circuit-level, i.e., electronic control method. The above-mentioned prior art document does not provide a method for remotely controlling a manual load-disconnecting device using mechanical means.

[0010] Korean Patent Document No. 10-1749553 discloses a remote operation and monitoring device for a passive load-switching ground transformer. Specifically, the device includes a remotely controlled ground switch and a server that performs distribution intelligence operation for the passive load-switching ground transformer, enabling remote operation and monitoring.

[0011] However, the above-mentioned prior document discloses a remote operation and monitoring device for a passive load-switching ground transformer, which is assumed to be controlled by a server. In other words, the above-mentioned prior document also does not provide a method for remotely operating a ground transformer or monitoring device in a mechanical manner.

[0082]

[0083] Referring to FIGS. 1 and 2, an electric opening / closing device (10) according to an embodiment of the present invention is illustrated. The electric opening / closing device (10) according to an embodiment of the present invention can be detachably coupled to a panel (20) and used (see FIGS. 29 to 33).

[0084] At this time, the electric opening / closing device (10) can be operated automatically rather than manually. That is, the electric opening / closing device (10) can perform the opening / closing operation of the electronic device housed inside the panel (20) by an electric signal rather than an external force applied by an operator.

[0085] Accordingly, the operator can control the electric switch (10) remotely without being located adjacent to the electric switch (10). Accordingly, the operator can control the electric switch (10) from a distance from the panel (20), thereby ensuring safety.

[0086] Furthermore, since the electric opening / closing device (10) operates according to an electrical signal to perform the opening / closing operation, the completion of the opening / closing operation can be accurately determined. Accordingly, the operator no longer needs to visually confirm the completion of the opening / closing operation, thereby improving the convenience of the opening / closing operation.

[0087] The electric switch (10) can be electrically connected to a remote controller. An operator can perform the opening and closing operation by simply controlling the remote controller while being away from the electric switch (10) or panel (20).

[0088] The electric opening / closing device (10) may be of any shape that can perform an opening / closing operation by being combined with a panel (20). In the illustrated embodiment, the electric opening / closing device (10) has a length in the front-back direction, a width in the left-right direction, and a height in the up-down direction, but is in the shape of a bar whose length is formed to be longer than the width or the height.

The position of the cable opening (113) may be changed to correspond to the position of the control unit (500).

[0109] The cable opening (113) may have any shape that can communicate with the first frame space (112) and the outside. In the illustrated embodiment, the cable opening (113) is formed as a disk-shaped space having a circular cross-section and a thickness in the vertical direction.

[0110] The second frame (120) constitutes another part of the frame section (100). A space is formed inside the second frame (120) to accommodate another configuration of the electric opening / closing device (10).

[0111] The second frame (120) may have a shape corresponding to the overall shape of the frame portion (100) or the shape of the first frame (110). In the illustrated embodiment, the second frame (120) is formed so that the length in the front-back direction is longer than the width in the left-right direction and the height in the up-down direction.

[0114] The second frame (120) is coupled with the third frame (130). One longitudinal side of the second frame (120), i.e., the rear side, can be coupled with one longitudinal side of the third frame (130), i.e., the front side in the illustrated embodiment.

[0115] In the illustrated embodiment, the second frame (120) includes a second frame surface (121), a second frame space (122), and a confirmation opening (123).

[0116] The second frame surface (121) constitutes the outer shape of the second frame (120).

One of the second frame surfaces (121) extends to surround the second frame space (122) in the thickness direction, i.e., from the upper side. The other of the second frame surfaces (121) extends to surround the second frame space (122) in the thickness direction, i.e., from the front side.

[0119] The second frame space (122) can be defined as a space formed inside the second frame (120). The second frame space (122) is defined by being at least partially surrounded by a plurality of second frame faces (121). In the illustrated embodiment, the second frame space (122) is surrounded by a plurality of second frame faces (121) on each side in the width direction, i.e., the left and right sides, one side in the height direction, i.e., the upper side, and one side in the length direction, i.e., the front side.

One height-wise side of the second frame space (122), in the illustrated embodiment, the lower side, is formed open and connected to the first frame space (112) and the outside.

[0121] Furthermore, the other side in the height direction of the second frame space (122), in the illustrated embodiment, the upper side, is connected to the outside by a confirmation opening (123).

[0122] The second frame space (122) may have a shape corresponding to the shape of the second frame surface (121). In the illustrated embodiment, the second frame space (122) has a rectangular cross-section and is formed as a polygonal prism-shaped space having a length in the front-back direction.

[0123] The inspection opening (123) provides a window for the operator to externally inspect the second frame space (122). As described above, the electric opening / closing device (10) according to the embodiment of the present invention can be opened / closed remotely. However, in some cases, the operator may need to directly inspect the current status. In such cases, the operator can inspect the second frame space (122) through the inspection opening (123).

[0124] At this time, the confirmation opening (123) may be closed by any member formed of a transparent material. This is because if the confirmation opening (123) is left open, there is a risk that foreign substances, etc. may enter, or byproducts generated in the second frame space (122) may be discharged to the outside.

[0139] The rail section (200) provides a path along which the moving section (700) moves. The moving section (700) is movably coupled to the rail section (200) and can move along the rail section (200) as the power section (400) operates. At this time, as will be described later, the moving section (700) can move linearly along the rail section (200) by the rotational force provided by the power section (400).

[0140] To this end, the rail part (200) and the moving part (700) are screw-fitted so that the rotational force applied to the rail part (200) can be converted into linear motion of the moving part (700).

[0141] The rail portion (200) is coupled to the frame portion (100). The rail portion (200) is accommodated in the frame portion (100) and can be supported by the frame portion (100).

[0143] The rail section (200) is coupled to the power section (400). The rail section (200) can receive rotational power from the power section (400). In the illustrated embodiment, one longitudinal side of the rail section (200), in the illustrated embodiment, the rear side, is coupled to the power section (400).

[0144] The rail section (200) is coupled to the link section (600). Specifically, the rail section (200) is coupled to the link section (600) via the moving section (700). The rail section (200) supports the link section (600) coupled to the moving section (700) so that it can rotate and link.

[0145] The rail part (200) is coupled to the moving part (700). The rail part (200) can support the moving part (700) so that it can move linearly.

[0147] The rail member (210) constitutes the body of the rail section (200). The rail member (210) is a portion where the rail section (200) is coupled to the power section (400). The rail member (210) is coupled to the motor member (410) and can rotate by receiving rotational force applied by the motor member (410).

[0148] The rail member (210) is coupled to the moving part (700) and supports the moving part (700) so that it can move. As described above, the rotational force applied to the rail member (210) can be converted into linear motion of the moving part (700).

[0149] The rail member (210) may have a shape corresponding to the movement path of the moving part (700). In the illustrated embodiment, the rail member (210) has a circular cross-section and a cylindrical shape having a length in the front-rear direction. In this case, screw threads may be formed on the outer periphery of the rail member (210). That is, the moving part (700) may be movably screw-connected to the rail member (210).

[0150] Therefore, when the rail member (210) is rotated by the motor member (410), the moving part (700) can move linearly in the longitudinal direction of the rail member (210), or in the forward and backward direction in the illustrated embodiment, along the screw thread of the rail member (210).

A groove is formed inside the motor member coupling end (211) so that the motor member (410) can be inserted and coupled.

[0154] At this time, in order to prevent the motor member joining end (211) from being loosened by the rotational force applied by the motor member (410), the cross-section of the groove may be formed in a polygonal or asymmetrical shape.

[0155] The rail support frame (220) rotatably supports the rail member (210). The rail member (210) can be rotated while being coupled to the rail support frame (220).

[0156] The rail support frame (220) is a portion where the rail portion (200) is connected to the frame portion (100). The rail support frame (220) can be fixedly connected to the first frame (110). Accordingly, the rail member (210) can be stably and rotatably supported on the rail support frame (220).

[0157] Additionally, the rail support frame (220) may be configured to limit the distance that the moving part (700) moves along the rail member (210). That is, as will be described later, when the rail support frame (220) comes into contact with the movement limiting member (740), further movement of the moving part (700) may be blocked.

[0158] A plurality of rail support frames (220) may be provided. The plurality of rail support frames (220) may rotatably support the rail member (210) at different positions.

In one embodiment, a through hole may be formed inside the second rail support frame (222) to which the rear side end of the rail member (210) is coupled.

[0162] At this time, the motor member joining end (211) can extend through the second rail support frame (222) to the motor member (410).

[0191] The link part (600) converts the linear motion of the moving part (700) into a rotational motion, thereby rotating a lever (not shown) provided on the panel (20).

[0192] The link portion (600) is coupled to the frame portion (100). The link portion (600) is movably accommodated in the first frame space (112) and the second frame space (122).

[0193] The link part (600) is coupled to the moving part (700). The link part (600) can move linearly together with the moving part (700). At this time, some components of the link part (600) are fixedly coupled to the moving part (700), so that the linear movement of the moving part (700) can be converted solely into a rotational movement for rotating a lever (not shown).

[0194] In the embodiments illustrated in FIGS. 8 to 11, the link portion (600) includes a link arm (610), a link connector (620), a link shaft member (630), a link pin (640), and a fastening member (650).

[0195] The link arm (610) is a configuration in which the link portion (600) is coupled to the moving portion (700). The link arm (610) extends along the longitudinal direction of the frame portion (100) or the moving direction of the moving portion (700). In the illustrated embodiment, the link arm (610) extends in the forward-backward direction.

[0196] One longitudinal side of the link arm (610), in the illustrated embodiment the front side, is rotatably coupled to the link connector (620) by a link shaft member (630).

At this time, the other side of the link arm (610) can be fixedly coupled to the link coupling frame (730).

[0197] Accordingly, the link arm (610) and other configurations of the link portion (600) coupled thereto can be moved together with the moving portion (700), but the coupling angle of the link arm (610) and the link coupling frame (730) can be maintained constant.

[0198] The link arm (610) can be any shape that rotatably supports the link connector (620) and can be fixedly connected to the moving part (700) and moved together. In the illustrated embodiment, the link arm (610) is formed in a plate shape having a length in the front-back direction and a thickness in the left-right direction.

[0199] A plurality of link arms (610) may be provided. The plurality of link arms (610) may be respectively coupled to the link connector (620) and the link coupling frame (730) at different locations. In the illustrated embodiment, the link arms (610) are provided in pairs and spaced apart from each other on the left and right sides. Each pair of link arms (610) is respectively coupled to each pair of link coupling frames (730a, 730b).

[0200] The link connector (620) is a portion where the link portion (600) is connected to the lever (not shown) of the panel (20). A hollow space is formed inside the link connector (620), so that the lever (not shown) can be inserted and connected.

[0201] The link connector (620) is coupled to the link arm (610). Specifically, the link connector (620) is rotatably coupled to the link arm (610) by a link shaft member (630). In the illustrated embodiment, the link connector (620) is positioned adjacent to one longitudinal side of the link arm (610), i.e., the front end.

[0202] The link connector (620) is positioned adjacent to the link pin (640). On each side of the width of the link connector (620) coupled with the link shaft member (630), in the illustrated embodiment, a link pin (640) is positioned. Accordingly, the coupling state between the link connector (620) and the link shaft member (630) can be stably maintained.

[0203] The link shaft member (630) is connected to the link arm (610) and the link connector (620), respectively. The link shaft member (630) rotatably connects the link connector (620) to the link arm (610). Therefore, it can be said that the link shaft member (630) functions as a rotational axis of the link connector (620).

[0204] In one embodiment, the link shaft member (630) can be detachably coupled to the link arm (610) and the link connector (620). Accordingly, when manual operation is required, the link shaft member (630) can be detached and the operating rod (R) can be coupled to the link connector (620). A detailed description thereof will be provided later.

[0205] The link shaft member (630) is coupled with a link pin (640). The longitudinal direction of the link shaft member (630), i.e., the left-right direction in the illustrated embodiment, can be fixed by the link pin (640).

[0206] The link shaft member (630) may be provided in any shape that can rotatably connect the link connector (620) to the link arm (610). In the illustrated embodiment, the link shaft member (630) has a cylindrical shape with a circular cross-section and a length in the left-right direction.

[0207] In the above embodiment, the link shaft member (630) can be penetratedly connected to the link arm (610) and the link connector (620), respectively.

[0208] The link pin (640) is configured to limit longitudinal movement of the link shaft member (630). The link pin (640) is positioned between the link arm (610) and the link connector (620), and is coupled with the link shaft member (630) to fix the position of the link shaft member (630).

[0209] Therefore, in order to separate the link shaft member (630) from the link arm (610) or link connector (620), a process of separating the link pin (640) from the link shaft member (630) must be performed first. Accordingly, the link shaft member (630) is prevented from being accidentally detached, thereby ensuring safety during operation.

[0210] The link pin (640) may be provided in any shape that can prevent arbitrary movement by being combined with the link shaft member (630). In one embodiment, the link pin (640) may be provided in the shape of an R-pin.

[0211] A plurality of link pins (640) may be provided. The plurality of link pins (640) may be coupled to the link shaft member (630) at different locations, and may each restrict arbitrary movement of the link shaft member (630). In the illustrated embodiment, a pair of link pins (640) are provided and are positioned facing each other with the link connector (620) interposed therebetween.

[0212] The fastening member (650) is a portion where the link portion (600) is fixedly connected to the lever (not shown) of the panel (20). After the lever (not shown) is inserted into the hollow space formed inside the link connector (620), the fastening member (650) is connected to the link connector (620) to maintain the lever (not shown) in the hollow space.

[0213] The fastening member (650) is coupled to the link connector (620). In the illustrated embodiment, a pair of fastening members (650) are provided, each coupled to the left and right sides of the link connector (620).

[0214] With the fastening member (650) provided, the link connector (620) can remain engaged with the lever (not shown) when the panel (20) needs to be manually operated. Accordingly, manual operation can be enabled simply by inserting the operating rod (R) into the hollow portion of the link connector (620). A detailed description thereof will be provided later.

[0215] The moving part (700) is coupled with the rail part (200) and moves linearly according to the rotation of the rail member (210). The moving part (700) is coupled with the link part (600) and moves together. As the moving part (700) moves, the link part (600) moves in a link manner, so that the lever (not shown) of the panel (20) can be rotated. That is, the moving part (700) can be defined as a configuration that moves so that the electric opening / closing device (10) automatically performs an opening / closing operation.

[0216] The moving part (700) is coupled to the frame part (100). Specifically, the moving part (700) is movably accommodated in the first frame space (112). The moving part (700) is not arbitrarily exposed to the outside of the frame part (100).

[0217] The moving part (700) is coupled to the rail part (200). Specifically, the moving part (700) is coupled to the rail member (210) so as to be able to move linearly. As described above, screw threads are formed on the outer periphery of the rail member (210), so it can be said that the moving part (700) is coupled to the rail member (210) so as to be able to move by screws.

[0218] The moving part (700) is positioned adjacent to the sensor part (300). At the first position (P1), the moving part (700) can come into contact with the second sensor (320). Additionally, at the second position (P2), the moving part (700) can come into contact with the first sensor (310). In the illustrated embodiment, the moving part (700) is positioned below the sensor part (300).

[0219] The moving part (700) is coupled to the link part (600). Specifically, the moving part (700) is fixedly coupled to the other end of the length direction of the link arm (610), i.e., the rear end in the illustrated embodiment. The moving part (700) can move together with the link part (600).

[0220] In the embodiments illustrated in FIGS. 18 to 21, the moving part (700) includes a moving body (710), a moving support frame (720), a link coupling frame (730), a moving limiting member (740), a transmission frame (750), an elastic member (760), and a transmission member (770).

[0221] The moving body (710) constitutes the body of the moving part (700). The moving body (710) is a portion where the moving part (700) is coupled to the rail member (210). The moving body (710) is movably coupled to the rail member (210).

[0222] A hollow space is formed inside the moving body (710). Screw threads may be formed on the inner periphery of the moving body (710) surrounding the hollow space. The screw threads may be screw-connected with screw threads formed on the outer periphery of the rail member (210) (see FIG. 17).

[0223] The moving body (710) is coupled to the moving support frame (720). The moving body (710) can be coupled to the link coupling frame (730) and the movement limiting member (740) by the moving support frame (720). In the illustrated embodiment, the front and rear sides of the moving body (710) are coupled to the moving support frame (720).

[0224] The moving body (710) is coupled with a link coupling frame (730). The moving body (710) can be coupled with the moving support frame (720) and the link arm (610) by the link coupling frame (730). In the illustrated embodiment, the left and right sides of the moving body (710) are coupled with the link coupling frame (730).

[0225] The moving body (710) is positioned adjacent to the transmission member (770). Specifically, the moving body (710) can at least partially accommodate the transmission member (770). As will be described below, when the moving part (700) moves, the transmission member (770) comes into contact with some component of the moving body (710), so that the moving body (710) can be prevented from moving.

[0226] The moving body (710) is movably coupled to the rail member (210) and may have any shape that can be coupled with other components of the moving part (700). In the illustrated embodiment, the moving body (710) has a cylindrical shape with a circular cross-section and a length in the front-back direction.

[0227] In the illustrated embodiment, the moving body (710) includes a bearing member (711), a transmission member receiving space (712), a limiting inclined surface (713), an outer circumferential inclined surface (714), a guide inclined surface (715), an inner circumferential inclined surface (716), a transmission member moving groove (717), and a rail coupling portion (718).

[0228] The bearing member (711) restricts the moving body (710) from moving along the screw-connected rail member (210) but from rotating. The bearing member (711) is coupled to the rail member (210) via a bearing shaft.

[0229] The bearing member (711) may be provided in any shape that can prevent rotation of the moving body (710). In one embodiment, the bearing member (711) may be provided in the shape of a ball bearing.

[0230] A plurality of bearing members (711) may be provided. The plurality of bearing members (711) may be configured to prevent rotation of the moving body (710) at different locations. In the illustrated embodiment, the bearing members (711) form ends on each side of the longitudinal direction of the moving body (710), i.e., the front side and the rear side.

[0231] A hollow space is formed through the interior of the bearing member (711). The hollow space is connected to a hollow space formed through the interior of the moving body (710), thereby providing a passage through which the rail member (210) can pass.

[0232] As the bearing member (711) is provided, only the portion of the moving body (710) located inside the bearing member (711), i.e., the portion where the transmission member receiving space (712) is received, can rotate. The rotation is limited by the transmission member (770), so that the moving body (710) can move in a straight line.

[0233] The transmission member receiving space (712) partially receives the transmission member (770) that transmits the rotational force of the rail member (210). The transmission member receiving space (712) is formed by being recessed into the outer periphery of the moving body (710). The transmission member receiving space (712) extends along the outer periphery direction of the moving body (710).

[0234] The transmission member receiving space (712) is defined by being surrounded by a limiting slope face (713), an outer perimeter slope face (714), a guide slope face (715), and an inner perimeter slope face (716). In the illustrated embodiment, each longitudinal side of the transmission member receiving space (712), i.e., the front side and the rear side, is surrounded by a pair of limiting slope faces (713), an outer perimeter slope face (714), a guide slope face (715), and an inner perimeter slope face (716).

[0235] The transmission member receiving space (712) is connected to the transmission member moving groove (717). The transmission member (770) may be allowed or restricted from moving from one of the transmission member receiving space (712) and the transmission member moving groove (717) to the other, depending on the rotational direction of the rail member (210).

[0236] The limiting slope surface (713) is configured to limit the movement of the transmission member (770) accommodated in the transmission member moving groove (717) to the transmission member receiving space (712). Depending on the rotational direction of the rail member (210), the transmission member (770) accommodated in the transmission member moving groove (717) can come into contact with the limiting slope surface (713). In this state, the transmission member (770) can press the limiting slope surface (713) to limit the moving body (710) from moving in the reverse direction.

[0237] The limiting slope surface (713) can be formed as a surface perpendicular to the rotational direction of the rail member (210). In the illustrated embodiment, the limiting slope surface (713) is formed as a surface extending radially from the outer periphery of the moving body (710) and having a length in the front-back direction.

[0238] The limiting slope surface (713) is continuous with the outer circumferential slope surface (714) at a predetermined angle. In one embodiment, the predetermined angle may be a right angle. Accordingly, the state transfer member (770) in contact with the outer circumferential slope surface (714) is prevented from moving in the direction toward the limiting slope surface (713).

[0239] The limiting slope surface (713) is continuous with the inner slant surface (716) at a predetermined angle. In one embodiment, the predetermined angle may be a right angle. The transmission member (770) moved along the inner slant surface (716) may enter the transmission member moving groove (717) and be positioned adjacent to the limiting slope surface (713).

[0240] The outer periphery inclined surface (714) guides the movement of the transmission member (770) together with the guide slant surface (715) and the inner periphery inclined surface (716). The outer periphery inclined surface (714) may be formed as a surface perpendicular to the movement direction of the moving body (710). In the illustrated embodiment, the outer periphery inclined surface (714) is formed as a surface that extends radially from the outer periphery of the moving body (710) and extends along the outer periphery.

[0241] The outer periphery inclined surface (714) is continuous with the limiting inclined surface (713) at a predetermined angle. As described above, the transmission member (770) positioned adjacent to the outer periphery inclined surface (714) cannot be moved directly to the limiting inclined surface (713).

[0242] The outer periphery inclined surface (714) is continuous with the guide slant surface (715) at a predetermined angle. In one embodiment, the predetermined angle may be an obtuse angle. The transmission member (770) positioned adjacent to the outer periphery inclined surface (714) can be moved toward the guide slant surface (715).

[0243] The outer slant surface (714) is positioned outside compared to the inner slant surface (716). That is, along the longitudinal direction of the moving body (710), the outer slant surface (714) is positioned closer to the bearing member (711) located at the end of the moving body (710) compared to the inner slant surface (716).

[0244] The guide slope surface (715) functions as a guide for the transfer member (770) positioned adjacent to the outer slope surface (714) to move to the inner slope surface (716). The guide slope surface (715) is positioned between the outer slope surface (714) and the inner slope surface (716), and is continuous with them respectively. The guide slope surface (715) may be formed as a surface extending along the outer circumference at a predetermined angle with respect to the movement direction of the moving body (710).

[0245] The transmission member (770) located on the outer slant surface (714) moves in the direction toward the guide slant surface (715), but does not move in the direction toward the limit slant surface (713).

[0246] The guide slope surface (715) is continuous with the outer slope surface (714) at a predetermined angle. In one embodiment, the predetermined angle may be an obtuse angle. In this case, the guide slope surface (715) may extend from the outer slope surface (714) toward the inner slope surface (716) in the longitudinal direction of the moving body (710), i.e., in a direction away from the bearing member (711).

[0247] The inner slant surface (716) guides the movement of the transmission member (770) together with the outer slant surface (714) and the guide slant surface (715). The inner slant surface (716) may be formed as a surface perpendicular to the movement direction of the moving body (710). In the illustrated embodiment, the inner slant surface (716) is formed as a surface that extends radially from the outer periphery of the moving body (710) and extends along the outer periphery.

[0248] The inner slant surface (716) is continuous with the guide slant surface (715) at a predetermined angle. In one embodiment, the predetermined angle may be an obtuse angle. The transmission member (770) moved along the guide slant surface (715) from the outer slant surface (714) may enter the inner slant surface (716).

[0249] The inner slant surface (716) is continuous with the limit slant surface (713) at a predetermined angle. In one embodiment, the predetermined angle may be a right angle. The transmission member (770) moved along the inner slant surface (716) enters the transmission member moving groove (717) and may be positioned adjacent to the limit slant surface (713).

[0250] The inner slant surface (716) is positioned inwardly compared to the outer slant surface (714). That is, along the longitudinal direction of the moving body (710), the inner slant surface (716) is positioned further from the bearing member (711) located at the end of the moving body (710) compared to the outer slant surface (714).

[0251] The transmission member moving groove (717) is a space defined by being partially surrounded by the limiting slope surface (713), the outer periphery slope surface (714), and the guide slope surface (715). The transmission member moving groove (717) is in communication with the transmission member receiving space (712). Depending on the rotational direction of the rail member (210), the transmission member (770) can be moved from one of the transmission member receiving space (712) and the transmission member moving groove (717) to the other.

[0252] The transfer member moving groove (717) may have a shape corresponding to the shapes of the limiting inclined surface (713), the outer periphery inclined surface (714), and the guide slanted surface (715). The outer side of the transfer member moving groove (717), that is, one side facing the bearing member (711) along the longitudinal direction of the moving body (710), is surrounded by the limiting inclined surface (713), the outer periphery inclined surface (714), and the guide slanted surface (715). The inner side of the transfer member moving groove (717), that is, the other side opposite the bearing member (711) along the longitudinal direction of the moving body (710), is in communication with the transfer member receiving space (712).

[0253] The above-described limiting slope surface (713), the outer circumferential slope surface (714), the guide slope surface (715), the inner circumferential slope surface (716), and the transmission member moving groove (717) may be provided in pairs. The pair of limiting slope surfaces (713), the outer circumferential slope surface (714), the guide slope surface (715), the inner circumferential slope surface (716), and the transmission member moving groove (717) may be spaced apart from each other in the longitudinal direction of the moving body (710), i.e., in the front-back direction, so as to face the transmission member receiving space (712).

[0254] At this time, along the outer circumferential direction of the moving body (710), a pair of limiting inclined surfaces (713), an outer circumferential inclined surface (714), a guide inclined surface (715), an inner circumferential inclined surface (716), and a transmission member moving groove (717) can be arranged opposite to each other.

[0255] That is, as best illustrated in Fig. 21, when viewed from the front side, a plurality of inner slanted surfaces (716), a guide slanted surface (715), an outer slanted surface (714), and a limiting slanted surface (713) are sequentially arranged in a clockwise direction on the front side.

[0256] Accordingly, when the moving body (710) rotates clockwise, the second transmission member (770b) arranged on the front side can sequentially pass through the outer slanted surface (714), the guide slanted surface (715), the inner slanted surface (716), and the limiting slanted surface (713). Accordingly, the rotation of the moving body (710) is not restricted.

[0257] Conversely, when the moving body (710) is rotated counterclockwise, the second transmission member (770b) arranged on the front side can come into contact with the limiting slope surface (713) to prevent further rotation of the moving body (710). Accordingly, the moving body (710) can be moved in a straight line toward one side of the longitudinal direction of the rail member (210).

[0258] Additionally, when viewed from the front side, a plurality of inner slanted surfaces (716), a guide slanted surface (715), an outer slanted surface (714), and a limiting slanted surface (713) are successively arranged in a counterclockwise direction on the rear side.

[0259] Accordingly, when the moving body (710) is rotated counterclockwise, the first transmission member (770a) arranged on the rear side can sequentially pass through the outer slanted surface (714), the guide slanted surface (715), the inner slanted surface (716), and the limiting slanted surface (713). Accordingly, the rotation of the moving body (710) is not restricted.

[0260] Conversely, when the moving body (710) is rotated clockwise, the first transmission member (770a) disposed on the rear side can come into contact with the limiting slope surface (713) to prevent further rotation of the moving body (710). Accordingly, the moving body (710) can be moved in a straight line toward the other side in the longitudinal direction of the rail member (210).

[0261] Accordingly, it will be understood that, depending on the direction of rotation of the rail member (210), the rotation of the moving body (710) in one direction is limited, so that the moving body (710) moves in a straight line.

[0262] The rail joint (718) is a hollow formed inside the moving body (710). The rail joint (718) is formed penetrating along the longitudinal direction of the moving body (710) and communicates with the hollow formed inside the bearing member (711). In one embodiment, the rail joint (718) may refer to the entire hollow formed inside the moving body (710).

[0263] The rail joint (718) may have a shape corresponding to the shape of the rail member (210). In the illustrated embodiment, the rail joint (718) is formed as a cylindrical space having a circular cross-section and a length in the front-rear direction.

[0264] As described above, screw threads may be formed on the inner periphery of the moving body (710) surrounding the rail joint (718). The screw threads may be screw-connected with screw threads formed on the outer periphery of the rail member (210).

[0265] The moving support frame (720) is a component that is coupled with the moving body (710). The moving support frame (720) is coupled with the moving body (710) and can move together. A plurality of moving support frames (720) are provided and can be coupled to each side of the length direction of the moving body (710), i.e., the front side and the rear side in the illustrated embodiment.

[0266] The moving support frame (720) is coupled with a link coupling frame (730). In the illustrated embodiment, each side of the width direction of the moving support frame (720), i.e., the left and right sides, is coupled with the link coupling frame (730). The link coupling frame (730) can be coupled with the moving body (710) by the moving support frame (720).

[0267] The movable support frame (720) is coupled to the movable limiting member (740). The movable support frame (720) movably supports the movable limiting member (740).

[0268] The moving support frame (720) may be composed of a plurality of pairs. The plurality of pairs of moving support frames (720) may be respectively coupled to the moving body (710) at different positions.

[0269] In the illustrated embodiment, the moving support frame (720) includes a first moving support frame (720a) positioned on the outside and a second moving support frame (720b) ​​positioned on the inside. The first moving support frame (720a) and the second moving support frame (720b) ​​are arranged to overlap each other and are each coupled to the moving body (710).

[0270] In the illustrated embodiment, the movable support frame (720) includes a movable through hole (721), a movable coupling protrusion (722), a limiting member through hole (723), and a sensor contact member (724).

[0271] A moving through hole (721) is formed through the inside of a moving support frame (720). A rail member (210) or a moving body (710) is connected through the moving through hole (721).

[0272] Specifically, a rail member (210) passes through a moving through hole (721) formed in a first moving support frame (720a) located on the outside. In addition, a moving body (710) passes through a moving through hole (721) formed in a second moving support frame (720b) ​​located on the inside.

[0273] The moving through hole (721) formed in each moving support frame (720a, 720b) ​​can be formed to have the same center as the cross section of the moving body (710) along the longitudinal direction of the moving body (710).

[0274] The movable coupling protrusion (722) is a portion where the movable support frame (720) is coupled to the link coupling frame (730). The movable coupling protrusion (722) is inserted and coupled into the link coupling groove (733) of the link coupling frame (730).

[0275] The movable coupling protrusion (722) is formed to protrude from each edge of the movable support frame (720) in the width direction, the left and right edges in the illustrated embodiment. The movable coupling protrusion (722) extends in the length direction of the movable support frame (720), in the vertical direction in the illustrated embodiment.

[0276] The restriction member through-hole (723) movably accommodates the movement restriction member (740). The restriction member through-hole (723) is formed through the interior of the movement support frame (720) so that the movement restriction member (740) can pass through it.

[0277] The limit member through hole (723) can be positioned apart from the movable through hole (721). In the illustrated embodiment, the limit member through hole (723) is positioned above the movable through hole (721).

[0278] The limiting member through-hole (723) may have a shape corresponding to the shape of the movement limiting member (740). In the illustrated embodiment, the limiting member through-hole (723) is formed as a polygonal plate-shaped space having a rectangular cross-section and a thickness in the front-back direction.

[0279] A plurality of limiting member through-holes (723) may be formed. The plurality of limiting member through-holes (723) may be respectively coupled to a plurality of movement limiting members (740). In the illustrated embodiment, a pair of limiting member through-holes (723) are formed for each movement support frame (720a, 720b).

[0280] The sensor contact member (724) is configured such that the moving member (700) sufficiently moved to the first position (P1) or the second position (P2) comes into contact with the sensor unit (300). The sensor contact member (724) is formed to protrude on one side in the height direction of the moving support frame (720), in the illustrated embodiment, on the upper side, so that it can come into contact with the sensor unit (300) located on the upper side of the rail member (210).

[0281] The sensor contact member (724) may protrude from the upper end of the first moving support frame (720a). The sensor contact member (724) may have any shape that can come into contact with the sensor unit (300). In the illustrated embodiment, the sensor contact member (724) is formed to extend inward along the length direction of the moving body (710) from the end of the first moving support frame (720a).

[0282] At the first position (P1), the sensor contact member (724) located on the rear side can come into contact with the second sensor (320). At the second position (P2), the sensor contact member (724) located on the front side can come into contact with the first sensor (310).

[0283] The link coupling frame (730) is another configuration that is coupled with the moving body (710). The link coupling frame (730) is indirectly coupled with the moving body (710) by the moving support frame (720). In the illustrated embodiment, the link coupling frame (730) is positioned on each side of the width direction of the moving body (710), i.e., on the left and right sides.

[0284] Additionally, the link coupling frame (730) is configured such that the moving part (700) is coupled to the link part (600). A link arm (610) is fixedly coupled to the link coupling frame (730).

[0285] The link coupling frame (730) is coupled with an elastic member (760). The movement limiting member (740) can be elastically supported by the link coupling frame (730).

[0286] The link coupling frame (730) may have any shape that can be coupled with the moving support frame (720), the link arm (610), and the elastic member (760). In the illustrated embodiment, the link coupling frame (730) is a polygonal plate having a rectangular cross-section and a thickness in the left-right direction.

[0287] A plurality of link coupling frames (730) may be provided. The plurality of link coupling frames (730) may be coupled to the movable support frame (720) and the elastic member (760) at different locations, respectively.

[0288] In the illustrated embodiment, the link coupling frame (730) is provided as a pair, including a first link coupling frame (730a) and a second link coupling frame (730b). The first and second link coupling frames (730a, 730b) are spaced apart from each other in the left and right directions and are positioned facing each other with the moving body (710) interposed therebetween.

[0289] In the illustrated embodiment, the link coupling frame (730) includes a link coupling shaft (731), an elastic member support protrusion (732), and a link coupling groove (733).

[0290] The link coupling shaft (731) is configured to couple the link coupling frame (730) with the link arm (610). The link coupling shaft (731) protrudes outward from the link coupling frame (730) and is coupled to a through hole (not shown) formed adjacent to the longitudinal end of the link arm (610), i.e., the rear end.

[0291] The elastic member support protrusion (732) is a configuration in which the link coupling frame (730) is coupled with the elastic member (760). The elastic member support protrusion (732) is formed to protrude from one side in the height direction of the link coupling frame (730), in the illustrated embodiment, from the upper side. One end of the elastic member (760) is coupled to the elastic member support protrusion (732).

[0292] At this time, the direction in which the elastic member support protrusion (732) protrudes may be different depending on the first and second link coupling frames (730a).

[0293] That is, the elastic member support protrusion (732) formed on the first link coupling frame (730a) positioned on the left protrudes toward the rear side. Accordingly, the first elastic member (760a) positioned relatively toward the rear side can apply an elastic force toward the rear side to the first movement limiting member (740a) coupled thereto.

[0294] In addition, the elastic member support protrusion (732) formed on the second link coupling frame (730b) positioned on the right side protrudes toward the front side. Accordingly, the second elastic member (760b) positioned relatively toward the front side can apply an elastic force toward the front side to the second movement limiting member (740b) coupled thereto.

[0295] The link coupling groove (733) is a configuration in which the link coupling frame (730) is coupled with the movable support frame (720). The link coupling groove (733) is formed to penetrate the inside of the link coupling frame (730) in the thickness direction, in the left-right direction in the illustrated embodiment, to accommodate the movable coupling protrusion (722).

[0296] The link coupling groove (733) may have a shape corresponding to the shape of the movable coupling protrusion (722). In the illustrated embodiment, the link coupling groove (733) is formed as a polygonal plate-shaped space extending in the vertical direction and having a thickness in the left-right direction.

[0297] At this time, the width of the link coupling groove (733), i.e., the length in the front-back direction in the illustrated embodiment, may be greater than the sum of the thicknesses of the movable coupling protrusions (722) formed on the first and second movable support frames (720a, 720b). That is, the link coupling groove (733) can simultaneously accommodate the movable coupling protrusions (722) formed on the first and second movable support frames (720a, 720b), respectively.

[0298] A plurality of link coupling grooves (733) may be formed. The plurality of link coupling grooves (733) are spaced apart in the longitudinal direction of the moving body (710), and in the front-back direction in the illustrated embodiment, so as to accommodate moving coupling protrusions (722) of different moving support frames (720).

[0299] In the illustrated embodiment, the link coupling grooves (733) are formed in pairs and spaced apart in the front-rear direction and are arranged facing each other with the link coupling axis (731) interposed therebetween.

[0300] The movement limiting member (740) is configured to prevent further movement of the moving part (700) by contacting the rail support frame (220) after the moving body (710) has moved to the first position (P1) or the second position (P2). By the movement limiting member (740), the moving part (700) is prevented from moving beyond the first position (P1) or the second position (P2).

[0301] The movement limiting member (740) is coupled to the movement support frame (720). The movement limiting member (740) can be movably penetrated through the restriction member through-hole (723).

[0302] The movement limiting member (740) is coupled to the transmission frame (750). Specifically, the movement limiting member (740) is coupled to the transmission frame (750) by the transmission member (770). The movement limiting member (740) may be covered by the transmission frame (750).

[0303] The movement limiting member (740) can receive elastic force from the elastic member (760). That is, the movement limiting member (740) is coupled to the transmission frame (750) by the transmission member (770), and the elastic member (760) is coupled to the transmission frame (750). Accordingly, the movement limiting member (740) can be moved or restored to its original position by the elastic force provided by the elastic member (760).

[0304] The movement limiting member (740) is coupled to the movement support frame (720) and may be provided in any shape that can prevent further movement of the moving part (700) by contacting the rail support frame (220). In the illustrated embodiment, the movement limiting member (740) is formed in a polygonal plate shape with a rectangular cross-section and a length in the front-back direction.

[0305] A plurality of movement limiting members (740) may be provided. The plurality of movement limiting members (740) may be spaced apart from each other and may be respectively coupled to a plurality of movement support frames (720), a plurality of transmission frames (750), a plurality of elastic members (760), and a plurality of transmission members (770).

[0306] In the illustrated embodiment, the movement limiting member (740) is provided as a pair including a first movement limiting member (740a) and a second movement limiting member (740b).

[0307] The first movement limiting member (740a) is positioned on the left side and is connected to the first transmission frame (750a), the first elastic member (760a), and the first transmission member (770a), respectively. The first movement limiting member (740a) is positioned to be biased toward the rear side compared to the second movement limiting member (740b).

[0308] Accordingly, when the moving part (700) is sufficiently moved to the second position (P2), the rear end of the first movement limiting member (740a) may come into contact with the second rail support frame (222) to limit further movement of the moving part (700).

[0309] In the above state, the first movement limiting member (740a) receives an elastic force in the direction toward the rear side by the first elastic member (760a). Therefore, the contact state between the first movement limiting member (740a) and the second rail support frame (222) can be stably maintained at the second position (P2).

[0310] The second movement limiting member (740b) is positioned on the right side and is connected to the second transmission frame (750b), the second elastic member (760b), and the second transmission member (770b), respectively. The second movement limiting member (740b) is positioned to be biased toward the front side compared to the first movement limiting member (740a).

[0311] Accordingly, when the moving part (700) is sufficiently moved to the first position (P1), the front end of the second movement limiting member (740b) may come into contact with the first rail support frame (221) to limit further movement of the moving part (700).

[0312] In the above state, the second movement limiting member (740b) receives an elastic force in the forward direction by the second elastic member (760b). Therefore, the contact state between the second movement limiting member (740b) and the first rail support frame (221) at the first position (P1) can be stably maintained.

[0313] The transmission frame (750) provides the force generated by the transmission member (770) to the movement limiting member (740). The transmission frame (750) is coupled to the movement limiting member (740) by the transmission member (770).

[0314] Specifically, a transmission frame (750) is formed therein, and a transmission member (770) is penetratedly connected thereto. At this time, the transmission member (770) is also penetratedly connected to the movement limiting member (740), so that the transmission frame (750) can move together with the movement limiting member (740) and the transmission member (770).

[0315] The transmission frame (750) is coupled to an elastic member (760). The transmission frame (750) can be moved toward one side of the longitudinal direction of the moving body (710) by an elastic force applied by the elastic member (760).

[0316] A plurality of transmission frames (750) may be provided. The plurality of transmission frames (750) may be spaced apart from each other and may be respectively coupled to a plurality of movement limiting members (740), a plurality of elastic members (760), and a plurality of transmission members (770).

[0317] In the illustrated embodiment, the transmission frame (750) includes a first transmission frame (750a) and a second transmission frame (750b).

[0318] The first transmission frame (750a) is positioned on the left side and is coupled to the first movement limiting member (740a), the first elastic member (760a), and the first transmission member (770a), respectively. The first transmission frame (750a) moves together with the first movement limiting member (740a) and the first transmission member (770a).

[0319] The first transmission frame (750a) receives an elastic force in the direction toward the second rail support frame (222), i.e., toward the rear side, by the first elastic member (760a).

[0320] The second transmission frame (750b) is positioned on the right side and is coupled to the second movement limiting member (750b), the second elastic member (760b), and the second transmission member (770b), respectively. The second transmission frame (750b) moves together with the second movement limiting member (740b) and the second transmission member (770b).

[0321] The second transmission frame (750b) receives elastic force in the direction toward the first rail support frame (221), i.e., toward the front side, by the second elastic member (760b).

[0322] In the illustrated embodiment, the transmission frame (750) includes an elastic member engaging projection (751).

[0323] The elastic member coupling protrusion (751) is a portion where the transmission frame (750) is coupled to the elastic member (760). The elastic member coupling protrusion (751) is formed to protrude from the outer edge in the width direction of the transmission frame (750).

[0324] At this time, the elastic member coupling protrusions (751) formed on the first and second transmission frames (750a, 750b) can extend in different directions.

[0325] That is, the elastic member coupling protrusion (751) formed on the first transmission frame (750a) extends toward the front side, and the elastic member coupling protrusion (752) formed on the second transmission frame (750b) extends toward the rear side.

[0326] Accordingly, the first transmission frame (750a) can be applied with elastic force in the direction toward the rear side, and the second transmission frame (750b) can be applied with elastic force in the direction toward the front side.

[0327] The elastic member (760) applies elastic force to the movement limiting member (740). Due to the elastic force applied by the elastic member (760), the movement limiting member (740) can be maintained in a state in which its end is in contact with the rail support frame (220). Accordingly, the moving part (700) that has been moved to the first position (P1) or the second position (P2) can be prevented from moving further.

[0328] Additionally, the transmission member (770) coupled with the transmission frame (750) can be maintained in a pressed state toward the inclined surface (713, 714, 715, 716) by the elastic member (760).

[0329] The elastic member (760) is coupled to the link coupling frame (730). Specifically, one side of the elastic member (760) in the longitudinal direction is coupled to the elastic member support protrusion (732).

[0330] The elastic member (760) is coupled to the transmission frame (750). Specifically, the other side of the elastic member (760) in the longitudinal direction is coupled to the elastic member coupling protrusion (751).

[0331] The elastic member (760) may be provided in any shape that can provide elasticity to the link coupling frame (730) and the transmission frame (750), respectively. In the illustrated embodiment, the elastic member (760) is provided in the shape of a coil spring.

[0332] A plurality of elastic members (760) may be provided. The plurality of elastic members (760) may be respectively coupled to the plurality of link coupling frames (730) and the plurality of transmission frames (750).

[0333] In the illustrated embodiment, the elastic member (760) includes a first elastic member (760a) and a second elastic member (760b).

[0334] The first elastic member (760a) is positioned on the left side and is coupled to the first link coupling frame (730a) and the first transmission frame (750a), respectively. The first elastic member (760a) applies an elastic force toward the rearward direction to the first movement limiting member (740a). At the same time, the first elastic member (760a) applies an elastic force toward the inclined surface (713, 714, 715, 716) on the rearward direction to the first transmission member (770a).

[0335] The second elastic member (760b) is positioned on the right side and is coupled to the second link coupling frame (730b) and the second transmission frame (750b), respectively. The second elastic member (760b) applies an elastic force toward the forward side to the second movement limiting member (740b). At the same time, the second elastic member (760b) applies an elastic force toward the forward side inclined surface (713, 714, 715, 716) to the second transmission member (770b).

[0336] Accordingly, each elastic member (760a, 760b) can maintain a contact state between the moving body (710) and the transmission member (770) while the rail member (210) rotates. Furthermore, each elastic member (760a, 760b) can maintain a contact state between the movement limiting member (740) and the rail support frame (220) at the first position (P1) or the second position (P2).

[0337] The transmission member (770) is coupled to the moving body (710) and configured to limit the rotation of the moving body (710) according to the rotation of the rail member (210). By the transmission member (770), the moving body (710) can move linearly according to the rotation of the rail member (210).

[0338] The transmission member (770) is coupled to the moving body (710). Specifically, the transmission member (770) is at least partially accommodated in the transmission member receiving space (712). The transmission member (770) can be moved between the transmission member receiving space (712) and the transmission member moving groove (717).

[0339] At this time, the transmission member (770) can be maintained in contact with any one of the inclined surfaces (713, 714, 715, 716). As described above, this can be achieved by the elastic force applied by the elastic member (760).

[0340] The transmission member (770) is coupled to the movement limiting member (740). The transmission member (770) is formed through a hole formed through the movement limiting member (740), and one end in the direction of extension, the lower end in the illustrated embodiment, is positioned in the transmission member receiving space (712).

[0341] The transmission member (770) is coupled to the transmission frame (750). The transmission member (770) penetrates a through hole formed inside the transmission frame (750).

[0342] Accordingly, it will be understood that the transfer member (770) can move together with the movement restriction member (740) and the transfer frame (750).

[0343] The transmission member (770) may be any shape that can be moved together with the movement limiting member (740) and the transmission frame (750) and can receive elastic force from the elastic member (760) at least while being coupled with the moving body (710).

[0344] In the illustrated embodiment, the transmission member (770) extends in the vertical direction, and one end in the extension direction, i.e., the upper end, has the shape of a bolt head. The other end in the extension direction of the transmission member (770), i.e., the lower end in the illustrated embodiment, is accommodated in the transmission member accommodation space (712) or the transmission member moving groove (717) and comes into contact with the inclined surfaces (713, 714, 715, 716).

[0345] A plurality of transmission members (770) may be provided. The plurality of transmission members (770) may be respectively coupled to a plurality of movement limiting members (740) and a plurality of transmission frames (750).

[0346] In the illustrated embodiment, the transmission member (770) includes a first transmission member (770a) and a second transmission member (770b).

[0347] The first transmission member (770a) is positioned so as to be biased toward the rear side on the left, and is coupled with the first movement limiting member (740a) and the first transmission frame (750a). The first transmission member (770a) is in contact with the inclined surfaces (713, 714, 715, 716) positioned at the rear side of the moving body (710), and is retractably received in the transmission member movement groove (717) positioned at the rear side.

[0348] The second transmission member (770b) is positioned so as to be biased toward the front side on the right, and is coupled with the second movement limiting member (740b) and the second transmission frame (750b). The second transmission member (770b) is brought into contact with the inclined surfaces (713, 714, 715, 716) positioned at the front side of the moving body (710), and is retractably received in the transmission member movement groove (717) positioned at the front side.

[0349]

[0350] Referring again to FIGS. 8 to 11 and FIGS. 22 to 27, the moving part (700) of the electric opening / closing device (10) according to an embodiment of the present invention is shown positioned at a first position (P1) and a second position (P2).

[0351] At the first position (P1) illustrated in FIGS. 8 to 11 and 22, the moving part (700) moves toward the rear. Accordingly, the first movement limiting member (740a) positioned to be biased toward the rear comes into contact with the second rail support frame (222).

[0352] In the above state, the first elastic member (760a) applies an elastic force toward the rearward direction to the first transmission frame (750a) and the first movement limiting member (740a) and the first transmission member (770a) coupled thereto. Accordingly, the first movement limiting member (740a) is maintained in contact with the second rail support frame (222), and the first transmission member (770a) is maintained in contact with the inclined surface (713, 714, 715, 716) located on the rearward side.

[0353] At this time, the sensor contact member (724) of the moving support frame (720) located on the rear side comes into contact with the second sensor (320) located on the rear side. Accordingly, the second sensor (320) generates detection information indicating that the moving part (700) has sufficiently moved to the first position (P1) and transmits this to the control part (500).

[0354] The control unit (500) controls the motor member (410) to stop operation to prevent further movement of the moving unit (700) using the generated detection information.

[0355] In the above state, the link connector (620) is rotated clockwise or counterclockwise to separate from the lever (not shown) provided on the panel (20).

[0356] At the second position (P2) illustrated in FIGS. 23 to 27, the moving part (700) moves forward. Accordingly, the second movement limiting member (740b) positioned to be biased toward the forward side comes into contact with the first rail support frame (221).

[0357] In the above state, the second elastic member (760b) applies an elastic force toward the forward side to the second transmission frame (750b) and the second movement limiting member (740b) and the second transmission member (770b) coupled thereto. Accordingly, the second movement limiting member (740b) is maintained in contact with the first rail support frame (221), and the second transmission member (770b) is maintained in contact with the inclined surface (713, 714, 715, 716) located on the forward side.

[0358] At this time, the sensor contact member (724) of the moving support frame (720) located on the front side comes into contact with the first sensor (310) located on the front side. Accordingly, the first sensor (310) generates detection information indicating that the moving part (700) has sufficiently moved to the second position (P2) and transmits this to the control part (500).

[0359] The control unit (500) controls the motor member (410) to stop operation to prevent further movement of the moving unit (700) using the generated detection information.

[0360] In the above state, the link connector (620) is rotated clockwise or counterclockwise and is coupled with a lever (not shown) provided on the panel (20).

[0361]

[0362] Meanwhile, in the embodiment illustrated in FIG. 22, the operation of the motor member (410) may continue even after the moving part (700) reaches the first position (P1). In this case, the first movement limiting member (740a) protruding toward the rear is temporarily pressed by the second rail support frame (222). Accordingly, the first transmission member (770a) pressing the limiting slope surface (713) moves toward the front and is separated from the slope surfaces (713, 714, 715, 716) on the rear side.

[0363] Accordingly, damage to the inclined surfaces (713, 714, 715, 716) by the first transmission member (770a) can be prevented.

[0364] Likewise, in the embodiment illustrated in FIG. 23, the operation of the motor member (410) may continue even after the moving part (700) reaches the second position (P2). In this case, the second movement limiting member (740b) protruding toward the front is temporarily pressed by the first rail support frame (221). Accordingly, the second transmission member (770b) pressing the limiting slope surface (713) moves toward the rear and is separated from the slope surfaces (713, 714, 715, 716) on the front side.

[0365] Accordingly, damage to the inclined surfaces (713, 714, 715, 716) by the second transmission member (770b) can be prevented.

[0366]

[0367] Referring to FIGS. 28 to 33, a process in which an electric switch (10) according to an embodiment of the present invention is separated from a panel (20) and an operating rod (R) is coupled is illustrated as an example. The above process can be performed when the electric switch (10) malfunctions or manual operation is required.

[0368] Referring to FIGS. 28 and 29, a state in which the electric opening / closing device (10) is coupled to the panel (20) is illustrated. In this state, the moving part (700) is in a second position (P2), that is, the second movement limiting member (740b) is in contact with the first rail support frame (221), and the moving support frame (720) located on the front side is in contact with the first sensor (310).

[0369] At this time, the link connector (620) is coupled with a lever (not shown) provided on the panel (20).

[0370] Referring to FIG. 30, first, the link pin (640) coupled with the link shaft member (630) is removed. Accordingly, the link shaft member (630) can be separated from the link arm (610) and the link connector (620).

[0371] Referring to FIGS. 31 and 32, the link shaft member (630) is separated from the link arm (610) and the link connector (620). Accordingly, the link connector (620) is released from the link arm (610). In this state, the link connector (620) is maintained in a state of being coupled to a lever (not shown) by a fastening member (650).

[0372] In the above state, when the operating rod (R) is inserted into the hollow of the link connector (620) and then rotated as shown in Fig. 33, the panel (20) can be manually operated.

[0373] That is, even when an electric opening / closing device (10) is provided, if manual operation is required, manual operation can be performed by combining the operating rod (R) with the link connector (620) while the link connector (620) is combined with a lever (not shown).

[0374] Therefore, there is no need to additionally equip a separate configuration for automatic or manual operation, so cost-effectiveness can be improved.

[0375]

[0376] Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
