The transmission structure is either complex, or the function is relatively simple and the reliability is not high, or the layout is unreasonable, resulting in a large size.

[0007] (4) When the spindle is in the main power on position and the standby power on position, there is no limit structure for the spindle, and it is impossible to prevent other mechanisms outside the operating mechanism from causing the spindle to flip.

[0057] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the present utility model. The protection scope of the present utility model is not limited to the description of the following embodiments.

[0058] A transfer switch typically includes an operating mechanism and a switch contact system (not shown). The operating mechanism is connected to the switch contact system via a main shaft 6. The switch contact system is connected to both the main power supply and the backup power supply. Rotation of the main shaft 6 drives the switch contact system to switch between the main power supply supplying the load or the backup power supply supplying the load. For a three-position transfer switch, the operating mechanism drives the main shaft 6 to rotate between three positions: the main power closed position, the double open position, and the backup power closed position. When the main shaft 6 rotates to the main power closed position, the double open position, or the backup power closed position, it drives the switch contact system to switch to the main power connected state, the main power and backup power disconnected state, or the backup power connected state, respectively.

[0059] Reference this application Figure 1 、 Figure 2a The operating mechanism of the transfer switch includes an energy storage mechanism connected to the main shaft 6, as well as a manual operating mechanism and / or an automatic operating mechanism. The energy storage mechanism includes a first energy storage mechanism 1, a second energy storage mechanism 2 and a flip member 3. The flip member 3 is rotatably arranged. The flip member 3 rotates to drive the first energy storage mechanism 1 or the second energy storage mechanism 2 to store energy first, and after driving the first energy storage mechanism 1 or the second energy storage mechanism 2 to cross the equilibrium position (dead point position), the first energy storage mechanism 1 or the second energy storage mechanism 2 releases energy to drive the main shaft 6 to quickly rotate and switch positions. The automatic operating mechanism is used to realize remote control to drive the energy storage mechanism to realize power conversion and disconnection, and the manual operating mechanism is used to manually drive the energy storage mechanism to realize power conversion and disconnection. The first energy storage mechanism 1 and the second energy storage mechanism 2 have the same structure. One is used for switching the main power on and off, and the other is used for switching the backup power on and off.

[0060] The flip member 3 can be rotated to the first position of the flip member, the middle position of the flip member and the second position of the flip member, which correspond to driving the main shaft 6 to rotate to the main power closing position, the double-open position and the backup power closing position respectively; when the flip member 3 rotates from the middle position of the flip member to the first position of the flip member, or from the first position of the flip member to the middle position of the flip member, the first energy storage mechanism 1 is driven to store energy first and release energy after crossing the equilibrium position (dead point position), directly or indirectly driving the main shaft 6 to rotate to the corresponding main power closing position or double-open position; when the flip member 3 rotates from the middle position of the flip member to the second position of the flip member, or from the second position of the flip member to the middle position of the flip member, the second energy storage mechanism 2 is driven to store energy first and release energy after crossing the equilibrium position (dead point position), directly or indirectly driving the main shaft 6 to rotate to the corresponding backup power closing position or double-open position, which is the existing technology in this field.

[0061] like Figure 1 、 Figure 2a As shown, an operating mechanism of this embodiment includes a housing 10 and an energy storage mechanism disposed within the housing 10. The housing 10 of this embodiment includes a base 101 and a bracket 102 disposed on the base 101. The bracket 102 includes a first side plate 103 and a second side plate 104 spaced apart from each other. The first side plate 103 and the second side plate 104 are connected by a plurality of fixed shafts. The energy storage mechanism includes a first energy storage mechanism 1, a second energy storage mechanism 2, and a flip member 3. The first energy storage mechanism 1, the second energy storage mechanism 2, and the flip member 3 are disposed between the first side plate 103 and the second side plate 104. The first energy storage mechanism 1 and the second energy storage mechanism 2 have the same structure and are symmetrically disposed on either side of the flip member 3. The main shaft 6 is rotatably disposed and passes through the middle of the first side plate 103 and the second side plate 104. The operating mechanism also includes a manual operating mechanism and an automatic operating mechanism. The automatic operating mechanism of this embodiment includes a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are mounted on the base 101 and symmetrically disposed on either side of the flip member 3 to drive the flip member 3 to rotate. The manual operating mechanism of this embodiment includes a toggle member 4, which is connected to the flip member 3 and rotatably disposed between the first side plate 103 and the second side plate 104, for driving the flip member 3 to rotate. In other embodiments, the housing 10 may also include an upper cover to cover the bracket 102; or the bracket 102 may also be a relatively closed housing structure; or the base 101 may be omitted, with the first and second electromagnetic mechanisms 7 and 8 also mounted on the bracket 102.

[0062] One of the improvements of this application is the driving cooperation structure between the automatic operating mechanism and the flip member 3. Figure 2aAs shown, the automatic operating mechanism of this embodiment includes a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8. The first electromagnetic mechanism 7 is used to drive the flip member 3 to rotate from the second position of the flip member to the middle position of the flip member, and from the middle position of the flip member to the first position of the flip member. The second electromagnetic mechanism 8 is used to drive the flip member 3 to rotate from the first position of the flip member to the middle position of the flip member, and from the middle position of the flip member to the second position of the flip member, and the first energy storage mechanism 1 or the second energy storage mechanism 2 is driven by the flip member 3 to drive the main shaft 6 to rotate.

[0063] like Figure 2a and Figure 14 As shown, the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 each include an electromagnetic component and a moving rod 782 connected to the electromagnetic component. The moving rod 782 is provided with a moving rod driving part 7822. When the electromagnetic component is energized, it drives the moving rod 782 to move and drive the flip part 3 to rotate. When the electromagnetic component is de-energized, the moving rod 782 is reset. The electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are respectively the first electromagnetic component 71 and the second electromagnetic component 81. The two moving rods 782 of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are respectively the first moving rod 72 and the second moving rod 82. The two moving rod driving parts 7822 of the first moving rod 72 and the second moving rod 82 are respectively the first moving rod driving part 722 and the second moving rod driving part 822.

[0064] In this embodiment, the first moving rod driving portion 722 and the second moving rod driving portion 822 are hook structures used to pull the flip member 3 to rotate. When the first electromagnetic component 71 is energized, the first moving rod 72 pulls the flip member 3. When the first electromagnetic component 71 is de-energized, the first moving rod 72 resets the first moving rod. When the second electromagnetic component 81 is energized, the second moving rod 82 pulls the flip member 3. When the second electromagnetic component 81 is de-energized, the second moving rod 82 resets the second moving rod. The first electromagnetic component 71 and the second electromagnetic component 81 typically include a moving iron core, a stationary iron core, and a reaction spring located between the moving iron core and the stationary iron core, which is conventional in the art. The first moving rod 72 and the second moving rod 82 are connected to the moving iron cores of the first electromagnetic component 71 and the second electromagnetic component 81, respectively.

[0065] like Figure 2a and Figure 9 、 Figure 11 As shown, the flip member 3 is provided with a third linkage portion 35 and a fourth linkage portion 36 spaced apart from each other. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 drive the flip member 3 to rotate via the third linkage portion 35 and the fourth linkage portion 36. In this embodiment, the third linkage portion 35 and the fourth linkage portion 36 are convex shafts on the flip member 3. Figure 2aAs shown, when the flip member 3 is in the middle position of the flip member, the third linkage part 35 and the fourth linkage part 36 are located between the two moving rod driving parts 7822 of the first moving rod 72 and the second moving rod 82. When the first electromagnetic mechanism 7 is energized, it can drive the first moving rod 72 to move, and the first moving rod driving part 722 drives the third linkage part 35 to drive the flip member 3 to rotate from the middle position of the flip member to the first position of the flip member. Alternatively, when the second electromagnetic mechanism 8 is energized, it can drive the second moving rod 82 to move, and the second moving rod driving part 822 drives the fourth linkage part 36 to drive the flip member 3 from the middle position of the flip member to the second position of the flip member. Figure 2a The first electromagnetic component 71 and the second electromagnetic component 81 are symmetrically arranged on both sides of the flip member 3. In the figure, the first electromagnetic component 71 is located on the right side and the second electromagnetic component 81 is located on the left side. When the flip member 3 is in the middle position of the flip member, the first moving rod driving part 722 at the end of the first moving rod 72 connected to the first electromagnetic component 71 extends to the left side of the third linkage part 35 and the fourth linkage part 36, and the second moving rod driving part 822 at the end of the second moving rod 82 connected to the second electromagnetic component 81 extends to the right side of the third linkage part 35 and the fourth linkage part 36. The first moving rod driving part 722 is close to the third linkage part 35 and there is a gap between it and the third linkage part 35, and the second moving rod driving part 822 is close to the fourth linkage part 36 and there is a gap between it and the fourth linkage part 36. At this time, the first electromagnetic component 71 can pull the third linkage part 35 through the first moving rod driving part 722 to drive the flip member 3 to rotate counterclockwise to the first position of the flip member, and the fourth linkage part 36 uses the gap between the second moving rod driving part 822 to rotate with the flip member 3 out of the gap between the first moving rod driving part 722 and the second moving rod driving part 822 (as shown in FIG. Figure 4a As shown), the first electromagnetic component 71 is then powered off and the first moving rod 72 is reset; the second electromagnetic component 81 can also pull the fourth linkage part 36 through the second moving rod driving part 822 to drive the flip member 3 to rotate clockwise to the second position of the flip member, and the third linkage part 35 utilizes the gap between the first moving rod driving part 722 and the second moving rod driving part 822 to rotate with the flip member 3 out of the gap between the first moving rod driving part 722 and the second moving rod driving part 822 (as shown). Figure 6a As shown), the second electromagnetic component 81 is then powered off and the second moving rod 82 is reset.

[0066] like Figure 4a 、 Figure 4b As shown, when the flip member 3 is in the first flip position, the third linkage portion 35 is located between the two moving rod driving portions 7822, and the fourth linkage portion 36 rotates out between the two moving rod driving portions 7822. The second electromagnetic mechanism 8 is energized to drive the second moving rod 82 to move. The second moving rod driving portion 822 drives the third linkage portion 35 to drive the flip member 3 from the first flip position to the middle flip position. Figure 4a 、 Figure 4b When the flip member 3 is in the first position of the flip member, the second moving rod driving portion 822 at the end of the second moving rod 82 is close to the third linkage portion 35, and the fourth linkage portion 36 has rotated out between the first moving rod driving portion 722 and the second moving rod driving portion 822. At this time, the second electromagnetic component 81 can pull the third linkage portion 35 through the second moving rod driving portion 822 to drive the flip member 3 to rotate clockwise to the middle position of the flip member, and return to the Figure 2a and the first movable rod driving portion 722 is far away from the third linkage portion 35, even if the action can not pull the third linkage portion 35 again.

[0067] Similar, such as Figure 7a As shown, when the flip member 3 is in the second flip member position, the fourth linkage portion 36 is located between the two moving rod driving portions 7822, and the third linkage portion 35 rotates out between the two moving rod driving portions 7822. The first electromagnetic mechanism 7 is energized to drive the first moving rod 72 to move, and the first moving rod driving portion 722 drives the fourth linkage portion 36 to drive the flip member 3 from the second flip member position to the middle flip member position. Figure 7a When the flip member 3 is in the second position of the flip member, the first moving rod driving portion 722 at the end of the first moving rod 72 is close to the fourth linkage portion 36, and the third linkage portion 35 has rotated out between the first moving rod driving portion 722 and the second moving rod driving portion 822. At this time, the first electromagnetic component 71 can pull the fourth linkage portion 36 through the first moving rod driving portion 722 to drive the flip member 3 to rotate counterclockwise to the middle position of the flip member, and return to the Figure 2a and the second movable rod driving portion 822 is far away from the fourth linkage portion 36, even if the action can not pull the fourth linkage portion 36 again.

[0068] The automatic operating mechanism of the operating mechanism of this embodiment adopts the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8, which are faster than the motor action and improve the switching speed of the conversion switch. The first electromagnetic mechanism 7 can realize the main power closing state of the operating mechanism, and can also realize the operating mechanism to switch from the backup power closing state to the double-split state. The second electromagnetic mechanism 8 can realize the backup power closing state of the operating mechanism, and can also realize the operating mechanism to switch from the main power closing state to the double-split state; the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are not directly connected to the flip part 3, and will not affect other rotational relationships of the flip part 3. The first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 realize the three-position conversion by cooperating with the third linkage part 35 and the fourth linkage part 36 of the flip part 3. The cooperating structure is ingenious and compact, and the reliability is high.

[0069] It should be noted that the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 may also use a pushing method instead of a pulling method to drive the flip member 3 to rotate. As other embodiments, the automatic operating mechanism may not use the electromagnetic mechanism of this embodiment, but may use other methods such as motors and cylinders to directly or indirectly drive the flip member 3 to rotate.

[0070] like Figure 2a 、 Figure 14 As shown, the electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 both include a moving iron core and a moving rod mounting plate 783 fixedly connected to the moving iron core, the moving rod 782 is rotatably mounted on the moving rod mounting plate 783, the moving rod spring 784 is connected to the moving rod 782, and the moving rod spring 784 drives the moving rod 782 to rotate to a horizontal position and is limited and fixed to the moving rod mounting plate 783; when the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are powered off to reset the moving rod 782, the third linkage part 35 or the fourth linkage part 36 located on the moving rod reset path acts on the moving rod 782, so that the moving rod 782 overcomes the action of the moving rod spring 784 and rotates to avoid the third linkage part 35 or the fourth linkage part 36. When the electromagnetic component is energized, the movable iron core pulls the flip member 3 to rotate via the movable rod 782. When the first electromagnetic component 71 is de-energized, the movable iron core returns to its original position, and the third linkage portion 35 or the fourth linkage portion 36 acts on the inclined surface 7824 of the hook portion outside the movable rod driving portion 7822 of the movable rod 782, causing the movable rod 782 to rotate to avoid the third linkage portion 35 or the fourth linkage portion 36, overcoming the force of the movable rod spring 784. It should be noted that the movable rod mounting plate 783 can be integrally provided with the movable iron core, or can be provided separately and then fixedly connected.

[0071] like Figure 14 As shown, one end of the movable rod 782 has a mounting hole, serving as a movable rod mounting portion 7821, which is hinged to the movable rod mounting plate 783 via a mounting axis. The other end of the movable rod 782 has a hook structure, which serves as a movable rod driving portion 7822 for cooperating with the flip member 3. The electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 each drive their respective movable rods 782 via the hook structure to pull the flip member 3 to rotate. The inner side of the hook structure is used to pull the flip member 3 to rotate, and the outer side of the hook structure has an inclined surface serving as an inclined hook surface 7824. The movable rod 782 is also provided with a movable rod limiting portion 7823. The movable rod limiting portion 7823 and the movable rod driving portion 7822 are respectively located on either side of the movable rod mounting portion 7821. One end of the movable rod spring 784 is connected to the movable rod spring mounting hole 7825 on the lower side of the movable rod mounting portion 7821, and the other end is connected to the bracket 102. The moving rod spring 784 of this embodiment is a tension spring, but it can obviously also be a torsion spring or other elastic member.

[0072] refer to Figure 2aIn this embodiment, the electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are each provided with an external reaction spring 785. One end of the reaction spring 785 is connected to the movable rod mounting plate 783, and the other end is connected to the bracket 102. The reaction spring 785 is used to drive the movable iron core to reset. When the electromagnetic components of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8 are energized, the movable iron core overcomes the force of the reaction spring 785 and pulls the flip member 3 to rotate via the movable rod 782. After the electromagnetic components are de-energized, the reaction spring 785 drives the movable iron core to reset. An independent auxiliary bracket 105 can be provided within the bracket 102 for mounting the movable rod spring 784 and reaction spring 785 of the first electromagnetic mechanism 7 and the second electromagnetic mechanism 8. Alternatively, a corresponding mounting structure can be provided on the first side plate 103 or the second side plate 104 of the bracket 102. It should be noted that, as other embodiments, the reaction spring can also be provided within the electromagnetic component, located between the movable iron core and the static iron core, or reaction springs can be provided both inside and outside the electromagnetic component.

[0073] like Figure 14 As shown, the moving rod mounting plate 783 includes a vertically arranged first moving rod mounting plate 7831 and a second moving rod mounting plate 7832. The second moving rod mounting plate 7832 is fixedly connected to the moving iron core. The moving rod 782 is rotatably set on the first moving rod mounting plate 7831. The moving rod spring 784 drives the moving rod 782 to rotate to the top limit of the second moving rod mounting plate 7832. Two mounting holes are provided on the first moving rod mounting plate 7831, one for rotational mounting with the moving rod 782, and the other for installing the reaction spring 785.

[0074] Another improvement of the present application is that the operating mechanism also includes a toggle member 4, which can be used as part of a manual operating mechanism, and / or part of an automatic operating mechanism, and / or used to cooperate in locking the position of the flip member 3 and the main shaft 6.

[0075] The toggle member 4 is used as a manual operating mechanism to illustrate the cooperation structure of the toggle member 4 and the flip member 3. The manual operating mechanism of this embodiment includes a toggle member 4, which is drivingly connected to the flip member 3 and is used to drive the flip member 3 to rotate to the first position, the middle position and the second position. Figure 9 and Figure 13As shown, in this embodiment, the toggle member 4 is rotatably arranged, the flip member 3 is provided with a first linkage portion 34, and the toggle member 4 is provided with a second linkage portion 41. The toggle member 4 is linked to the flip member 3 through the second linkage portion 41; the toggle member 4 can be rotated to the toggle member first position, the toggle member middle position, and the toggle member second position, and the toggle member first position and the toggle member second position are symmetrically arranged on both sides of the toggle member middle position; when the toggle member 4 rotates to the toggle member first position, the toggle member middle position, and the toggle member second position, it drives the flip member 3 to rotate to the flip member first position, the flip member middle position, and the flip member second position respectively, and drives the first energy storage mechanism 1 or the second energy storage mechanism 2 to drive the main shaft 6 to rotate. Preferably, when the flip member 3 rotates to the flip member first position, the flip member middle position, and the flip member second position, it drives the toggle member 4 to rotate to the toggle member first position, the toggle member middle position, and the toggle member second position respectively, so that the toggle member 4 can play the role of indicating the state of the flip member 3. Obviously, as other embodiments, the rotation of the toggle member 4 unidirectionally drives the flip member 3 to rotate, while the rotation of the flip member 3 does not drive the toggle member 4, which is also possible and falls within the protection scope of this application.

[0076] In this embodiment, Figure 2a 、 Figure 9 and Figure 13 As shown, the first linkage portion 34 and the second linkage portion 41 are gears, and the flip member 3 and the toggle member 4 are linked by gear engagement. Obviously, as other embodiments, the flip member 3 and the toggle member 4 can also be driven and connected by means of a hinge, a drive rod and a drive groove, etc. For example, a drive groove can be provided on the flip member 3, and the toggle member 4 can be provided with a drive rod that cooperates with it. The drive rod is inserted into the drive groove and pushes on the side walls of the drive groove, thereby driving the flip member 3 to rotate in both directions. In addition, the toggle member 4 can also indirectly drive the flip member 3 through a transmission mechanism such as a connecting rod or a lever; all of these fall within the scope of protection of this application.

[0077] like Figure 13As shown, the toggle member 4 is provided with a toggle member driving portion 45 for manual operation, which is used to drive the toggle member 4 to rotate. In this embodiment, the toggle member driving portion 45 is a hole-shaped structure, which drives the toggle member 4 to rotate by inserting a drive rod. Obviously, as other embodiments, the toggle member driving portion 45 can also be a raised handle, which extends outside the housing of the operating mechanism, and drives the toggle member 4 to rotate by directly operating the handle. In addition, the manual operating mechanism can also include other transmission mechanisms, which can indirectly drive the toggle member 4 to rotate. If the toggle member 4 is driven by an electric mechanism, the toggle member 4 can be used as part of the automatic operating mechanism and is not used for the manual operating mechanism. For example, the automatic operating mechanism includes a first electromagnetic mechanism 7 and a second electromagnetic mechanism 8, each of which includes an electromagnetic component and a moving rod 782 connected to the electromagnetic component. When the electromagnetic component is energized, the moving rod 782 drives the toggle member 4 to rotate. Alternatively, the automatic operating mechanism includes a motor and a gear set connected to the motor. The motor drives the toggle member 4 to rotate through the gear set. An incomplete gear transmission can be used between the gear set and the toggle member 4.

[0078] Preferably, the toggle member 4 is used to drive an indicator mechanism to indicate the state of the operating mechanism. For example, the toggle member 4 has an indicator portion that indicates the state of the operating mechanism. In one alternative, the toggle member 4 is provided with an indicator rod (not shown) extending outside the housing of the operating mechanism as the indicator portion. An indicator mark is provided on the exterior of the operating mechanism housing. When the toggle member 4 is rotated to the first position, the intermediate position, and the second position, the indicator rod corresponds to a different indicator mark, respectively, to indicate the state of the operating mechanism. The indicator mechanism comprises the indicator portion and the indicator mark of the toggle member 4. Preferably, the handle also serves as the indicator rod. Two or three indicator marks may be provided on the exterior of the operating mechanism housing. In another alternative, the toggle member 4 is provided with multiple indicator marks (not shown) as the indicator portion. An indicator window is provided on the housing of the operating mechanism. When the toggle member 4 is rotated to the first position, the intermediate position, and the second position, different indicator marks correspond to the indicator window. The indicator mechanism comprises the indicator portion and the indicator window of the toggle member 4. As another embodiment, the indicating mechanism includes an indicating member, and the toggle member 4 drives the indicating member to move to indicate the state of the operating mechanism.

[0079] Another improvement of the present application is that a spindle locking mechanism 5 is provided for locking the spindle 6 in the main power closing position or the backup power closing position. When the flip member 3 rotates to the first position of the flip member, the spindle locking mechanism 5 is driven to lock the spindle 6, so that the spindle 6 cannot rotate to the double-split position. When the flip member 3 rotates to the middle position of the flip member, the spindle locking mechanism 5 is driven to release the lock on the spindle 6. When the flip member rotates to the second position, the spindle locking mechanism 5 is driven to lock the spindle 6, so that the spindle 6 cannot rotate to the double-split position, thereby avoiding other mechanisms outside the operating mechanism from driving the spindle 6 to flip, thereby improving reliability and safety.

[0080] like Figure 2d 、 Figure 11 and Figure 12 As shown, the spindle locking mechanism 5 of this embodiment includes a first lever 51 and a second lever 52, the first lever 51 is provided with a first lever locking portion 512, the second lever 52 is provided with a second lever locking portion 522, and the spindle 6 is provided with a first locking portion 541 and a second locking portion 542; when the flip member 3 moves to the first position of the flip member, it avoids the first lever 51, so that the first elastic member 53 drives the first lever 51 to drive the first lever locking portion 512 to move in the direction close to the spindle 6, and when the spindle 6 rotates to the main power closing position, the first locking portion 541 of the spindle 6 is locked with the first lever locking portion 512 so that the spindle 6 cannot rotate to the double-split position, thereby locking the spindle 6 in the main power closing position; when the flip member 3 moves to the second position of the flip member, it avoids the second lever 52, so that the second elastic member drives the second lever 52 to drive the first The second lever locking portion 522 moves in the direction close to the main shaft 6, and when the main shaft 6 rotates to the backup power closing position, the second locking portion 542 of the main shaft 6 is locked with the second lever locking portion 522, so that the main shaft 6 cannot rotate to the double-split position, and the main shaft 6 is locked in the backup power closing position; when the flip member 3 rotates from the first position of the flip member to the middle position of the flip member, the first lever 51 is driven to overcome the force of the first elastic member 53 to drive the first lever locking portion 512 to move in the direction away from the main shaft 6, and the locking cooperation with the first locking portion 541 of the main shaft 6 is released; when the flip member 3 rotates from the second position of the flip member to the middle position of the flip member, the second lever 52 is driven to overcome the force of the second elastic member to drive the second lever locking portion 522 to move in the direction away from the main shaft 6, and the locking cooperation with the second locking portion 542 of the main shaft 6 is released.

[0081] like Figure 2d 、 Figure 4c 、 Figure 5c 、 Figure 7b as well as Figure 8bA preferred embodiment is shown, in which the first elastic member 53 also serves as the second elastic member, that is, the first elastic member 53 and the second elastic member are the same elastic member, and the first elastic member 53 is connected between the first lever 51 and the second lever 52. Only one first elastic member 53 needs to be provided to simplify the structure.

[0082] In this embodiment, the spindle locking mechanism 5 further includes a baffle 54, which is fixedly mounted on the spindle 6, and a first locking portion 541 and a second locking portion 542 are mounted on the baffle 54. Figure 12 In this embodiment, a baffle mounting hole 543 is provided in the middle of the baffle 54. The baffle 54 is mounted on the main shaft 6 through the baffle mounting hole 543 and rotates integrally with the main shaft 6. In other embodiments, the baffle 54 can also be integrally formed with the main shaft 6, that is, the first locking portion 541 and the second locking portion 542 are directly provided on the main shaft 6.

[0083] In this embodiment, the flip member 3 drives the spindle locking mechanism 5 via the toggle member 4. When the flip member 3 rotates to the first flip position, the middle flip position, and the second flip position, the toggle member 4 correspondingly rotates to the first toggle position, the middle toggle position, and the second toggle position, respectively. When the toggle member 4 rotates to the first toggle position and the second toggle position, the spindle locking mechanism 5 is driven to lock the spindle 6, preventing the spindle 6 from rotating to the double-split position. When the toggle member 4 rotates to the middle toggle position, the spindle locking mechanism 5 is driven to release the lock on the spindle 6. Of course, the flip member 3 can also directly drive the first lever 51 and the second lever 52, or drive the first lever 51 and the second lever 52 through other transmission structures.

[0084] The first lever 51 is provided with a side edge of the first lever locking portion 512 and the second lever 52 is provided with a side edge of the second lever locking portion 522, which are arranged at opposite sides of the main shaft 6; when the toggle member 4 moves to the first position of the toggle member, it drives the second lever 52 to move in the direction away from the main shaft 6 and avoids the first lever 51, so that the first elastic member 53 drives the first lever 51 to drive the first lever locking portion 512 to move in the direction close to the main shaft 6. When the main shaft 6 rotates to the main power closing position, the first locking portion 541 of the main shaft 6 is locked with the first lever locking portion 512, so that the main shaft 6 cannot rotate to the double-open position; when the toggle member 4 moves to the second position of the toggle member, it drives the first lever 51 to move away from the main shaft 6. When the toggle member 4 is rotated from the first position of the toggle member to the middle position of the toggle member, the first lever 51 is driven to overcome the force of the first elastic member 53 to drive the first lever locking portion 512 to move in the direction away from the main shaft 6, thereby releasing the locking cooperation with the first locking portion 541 of the main shaft 6, and the first elastic member 53 drives the second lever 52 to reset; when the toggle member 4 is rotated from the second position of the toggle member to the middle position of the toggle member, the second lever 52 is driven to overcome the force of the first elastic member 53 to drive the second lever locking portion 522 to move in the direction away from the main shaft 6, thereby releasing the locking cooperation with the second locking portion 542 of the main shaft 6, and the first elastic member 53 drives the first lever 51 to reset.

[0085] like Figure 2a 、 Figure 2b 、 Figure 2cAs shown, another improvement of the present application lies in the structural design of the energy storage mechanism, and a new energy storage mechanism is provided, which includes a first energy storage mechanism 1, a second energy storage mechanism 2 and a flip member 3. The flip member 3 is rotatably arranged and is provided with a first circular arc slide 31 and a second circular arc slide 32. The first energy storage mechanism 1 and the second energy storage mechanism 2 each include a connecting rod mechanism and an energy storage spring. The connecting rod mechanism includes a pulling plate and a driven plate. One end of the energy storage spring is rotatably arranged, and the other end is connected to one end of the pulling plate. The other end of the pulling plate is hinged to the driven plate through a connecting rod shaft. The driven plate is rotatably arranged and is directly or indirectly connected to the main shaft 6. The connecting rod shafts of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively installed in the first circular arc slide 31 and the second circular arc slide 32 of the flip member 3. The connecting rod shafts of the first and second energy storage mechanisms 1 and 2 are capable of sliding within the corresponding first and second circular arc grooves 31 and 32. When the flip member 3 rotates, the corresponding connecting rod shaft is driven through one of the two end sidewalls of the first and second circular arc grooves 31 and 32 to drive the connecting rod mechanism of the first and second energy storage mechanisms 1 and 2 to move. This causes the corresponding energy storage spring to first store energy and then release energy after crossing the equilibrium position, driving the connecting rod mechanism to rotate the main shaft 6, and the connecting rod shaft slides to the other end of the first and second circular arc grooves 31 and 32. The two end sidewalls of the first circular arc groove 31 drive the connecting rod shaft to move in different directions.

[0086] The flip member 3 rotates through the first circular arc slot 31 to drive the connecting rod shaft of the first energy storage mechanism 1 to drive the connecting rod mechanism of the first energy storage mechanism 1 to move, so that the energy storage spring of the first energy storage mechanism 1 first stores energy and releases energy after crossing the equilibrium position. The energy storage spring of the first energy storage mechanism 1 releases energy and drives the connecting rod mechanism of the first energy storage mechanism 1 to move, thereby driving the main shaft 6 to rotate; or, the flip member 3 rotates through the second circular arc slot 32 to drive the connecting rod shaft of the second energy storage mechanism 2 to drive the connecting rod mechanism of the second energy storage mechanism 2, so that the energy storage spring of the second energy storage mechanism 2 first stores energy and releases energy after crossing the equilibrium position. The energy storage spring of the second energy storage mechanism 2 releases energy and drives the connecting rod mechanism of the second energy storage mechanism 2 to drive the main shaft 6 to rotate.

[0087] like Figure 2a 、 Figure 2b 、 Figure 9 and Figure 15As shown, the flip member 3 includes a first arc chute 31 and a second arc chute 32. In this embodiment, the flip member 3 is rotatably mounted on the main shaft 6 and rotates around the main shaft 6. Of course, the main shaft 6 can also be mounted on other rotating shafts instead of the shaft 6. The connecting rod mechanisms of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively the first connecting rod mechanism 12 and the second connecting rod mechanism 22, the energy storage springs of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively the first energy storage spring 11 and the second energy storage spring 21, and the connecting rod shafts of the first energy storage mechanism 1 and the second energy storage mechanism 2 are respectively the first connecting rod shaft 123 and the second connecting rod shaft 223. Among them, Figure 15 A structural schematic diagram of the first side panel of the present application is shown.

[0088] The pulling plate and the driven plate of the first connecting rod mechanism 12 are respectively the first driven plate 121 and the first pulling plate 122. The first driven plate 121 is rotatably arranged and connected to the main shaft 6. The first driven plate 121 is hinged to one end of the first pulling plate 122 through the first connecting rod shaft 123. The other end of the first pulling plate 122 is connected to one end of the first energy storage spring 11. The other end of the first energy storage spring 11 is connected to the first energy storage spring fixed shaft 1023 of the bracket 102. The first connecting rod shaft 123 is movably installed in the first arc slide groove 31 of the flip member 3. The flip member 3 drives the first connecting rod shaft 123 through the side wall of one end of the first arc sliding groove 31, driving the first driven plate 121 and the first pulling plate 122 to rotate, so that the first energy storage spring 11 first stores energy. After the first energy storage spring 11 passes the equilibrium position, the first energy storage spring 11 releases energy through the first pulling plate 122 and the first connecting rod shaft 123 to drive the first driven plate 121 to rotate, and the first driven plate 121 drives the main shaft 6 to rotate. The equilibrium position is as shown in FIG. Figure 3b In the example, the rotation axis of the first energy storage spring 11, the first driven plate 121 and the force direction of the first connecting rod shaft 123 are on the same straight line. After the first energy storage spring 11 releases energy, the first connecting rod shaft 123 slides to the side wall of the other end of the first arc groove 31.

[0089] The structure of the second connecting rod mechanism 22 is similar to that of the first connecting rod mechanism 12. The pulling plate and the driven plate of the second connecting rod mechanism 22 are respectively the second driven plate 221 and the second pulling plate 222. The second driven plate 221 is hinged to one end of the second pulling plate 222 through the second connecting rod shaft 223. The other end of the second pulling plate 222 is connected to one end of the second energy storage spring 21. The other end of the second energy storage spring 21 is connected to the second energy storage spring fixed shaft 1024 of the bracket 102. The second connecting rod shaft 223 is movably installed in the second arc slide groove 32 of the flip member 3. The flip member 3 drives the second connecting rod shaft 223 through the side wall of one end of the second arc slot 32, driving the second driven plate 221 and the second pulling plate 222 to rotate, so that the second energy storage spring 21 stores energy first. After the second energy storage spring 21 passes the equilibrium position, the second energy storage spring 21 releases energy and drives the second driven plate 221 to rotate through the second pulling plate 222 and the second connecting rod shaft 223. After the driven plate driving part 1213 contacts and limits the main shaft linkage part 61, the second driven plate 221 drives the main shaft 6 to rotate. After the second energy storage spring 21 releases energy, the second connecting rod shaft 223 slides to the side wall of the other end of the second arc slot 32.

[0090] The driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2, i.e., the first driven plate 121 and the second driven plate 221, can be directly or indirectly connected to the main shaft 6. In this embodiment, the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 are both provided with a driven plate rotation hole 1212, and a driven plate driving part 1213 is provided in the driven plate rotation hole 1212. A main shaft linkage part 61 is provided on the main shaft 6. The driven plate is sleeved on the main shaft 6 through the driven plate rotation hole 1212. The driven plate can rotate around the main shaft 6, and after the driven plate driving part 1213 contacts and limits the position with the main shaft linkage part 61, the driven plate drives the main shaft 6 to rotate. The operating mechanism of this embodiment directly installs the driven plate of the connecting rod mechanism on the main shaft 6. The driven plate can rotate around the main shaft 6, and after the driven plate driving part 1213 contacts and limits the position with the main shaft linkage part 61, the main shaft 6 is driven to rotate. No redundant transmission structure is required, and the structure is simple and compact.

[0091] In particular, when the flip member 3 drives the first energy storage mechanism 1 to store energy first and releases energy after crossing the equilibrium position, when the energy storage spring of the first energy storage mechanism 1 reaches the equilibrium position, or after crossing the equilibrium position, the driven plate driving portion 1213 of the driven plate of the first energy storage mechanism 1 contacts and limits the spindle linkage portion 61, that is, during the energy storage process before the energy storage spring of the first energy storage mechanism 1 reaches the equilibrium position, the driven plate of the first energy storage mechanism 1 rotates around the spindle 6, and the driven plate driving portion 1213 moves in a direction close to the spindle linkage portion 61, and the two do not contact and limit, and this process does not drive the spindle 6 to rotate. When the flip member 3 drives the second energy storage mechanism 2 to first store energy and then release the energy after crossing the equilibrium position, the driven plate driving portion 1213 of the driven plate of the second energy storage mechanism 2 only contacts and limits the spindle linkage portion 61 when the energy storage spring of the second energy storage mechanism 2 reaches the equilibrium position, or after crossing the equilibrium position. That is, during the energy storage process before the energy storage spring of the second energy storage mechanism 2 reaches the equilibrium position, the driven plate of the second energy storage mechanism 2 rotates around the spindle 6, and the driven plate driving portion 1213 moves in a direction approaching the spindle linkage portion 61. There is no contact and limit between the two, and this process does not drive the spindle 6 to rotate. In this way, the spindle 6 does not move during the energy storage mechanism's energy storage process. After the energy storage mechanism releases the energy, the spindle 6 is driven to rotate rapidly to switch the power supply. The switching speed of the automatic transfer switch is independent of the speed of the manual operating mechanism and the automatic operating mechanism. This ensures that the operating mechanism can quickly drive the spindle 6 to switch the power supply, reduces arc burning of the switch contact system, and improves the performance and reliability of the transfer switch.

[0092] Of course, as other inferior embodiments, the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 can also be sleeved on the main shaft 6 and fixedly connected to the main shaft 6 to rotate synchronously, but this solution requires a large operating force when performing opening and closing operations. As other inferior embodiments, the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 can also be rotatably arranged on both sides of the main shaft 6, and the main shaft 6 can be driven to rotate by the protruding structure on the outside of the driven plates, or the main shaft 6 can be indirectly driven to rotate by a transmission mechanism, for example, the transmission mechanism is driven by two incomplete gears, or the transmission mechanism is driven by a connecting rod and a slide groove, etc.

[0093] Specifically, such as Figure 10a-Figure 11As shown, the structures of the first driven plate 121 and the second driven plate 221 of this embodiment are similar, and both are provided with a driven plate rotation hole 1212. A protruding structure is provided in the driven plate rotation hole 1212 as a driven plate driving portion 1213. The main shaft 6 is provided with a main shaft linkage portion 61 that cooperates with the driven plate driving portion 1213. The main shaft 6 is provided with an arc side wall for rotating the driven plate rotation hole 1212, and a main shaft avoidance notch 62 for avoiding the driven plate driving portion 1213. The connection between the spindle avoidance notch 62 and the arc side wall also serves as the spindle linkage part 61. The driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 can rotate within the area corresponding to the driven plate driving part 1213 and the spindle avoidance notch 62. When the driven plate driving part 1213 rotates to the connection between the spindle avoidance notch 62 and the arc side wall, it contacts and limits the spindle linkage part 61. The rotation of the driven plates of the first energy storage mechanism 1 and the second energy storage mechanism 2 can drive the spindle 6 to rotate.

[0094] like Figure 11 As shown, the spindle 6 includes a first spindle connecting section 63, a spindle mounting section 64, a second spindle connecting section 65, and a spindle output section 66, which are arranged in sequence. The cross-section of the spindle mounting section 64 includes alternating arcuate sidewalls and planar sidewalls. The arcuate sidewalls are used for the rotation of the driven plate, and the gap formed in the planar sidewall serves as the spindle avoidance gap 62. The connection between the spindle avoidance gap 62 and the arcuate sidewalls constitutes the spindle linkage portion 61. In this embodiment, the cross-sections of the first spindle connecting section 63, the spindle mounting section 64, the second spindle connecting section 65, and the spindle output section 66 are all oval in shape, including two opposing arcuate sidewalls and two opposing planar sidewalls. The corresponding driven plates are also provided with two driven plate driving portions 1213. The first connecting section 63 and the second connecting section 65 of the main shaft correspond to the first side plate 103 and the second side plate 104 respectively. The main shaft mounting section 64 is located between the first side plate 103 and the second side plate 104 and is used to mount the first and second driven plates 121 and 221 and the flip member 3. The main shaft output section 66 is used to connect to the switch contact system. The baffle mounting groove 67 is also provided on the second connecting section 65 of the main shaft for mounting the baffle 54 ( Figure 12 Obviously, as other embodiments, the cross-sections of the first spindle connecting section 63, the second spindle connecting section 65, and the spindle output section 66 may also be other shapes, such as rectangles, polygons, etc.

[0095] It should be noted that one or more driven plate driving portions 1213 may be provided within the driven plate rotation hole 1212, and the corresponding number of spindle avoidance notches 62 may also be one or more. Furthermore, as another embodiment, the spindle avoidance notches 62 are groove structures formed on the arcuate sidewalls of the spindle, the driven plate driving portions 1213 extend into the groove structures, and the sidewalls on both sides of the groove structures serve as the spindle linkage portions 61. As another embodiment, the driven plate driving portions 1213 are groove structures within the driven plate rotation hole 1212, and the spindle linkage portions 61 are protrusions protruding radially from the spindle 6. The protrusions on the spindle 6 extend into the groove structures of the driven plate rotation hole 1212, allowing the driven plate to rotate around the arcuate sidewalls of the spindle 6 within the region corresponding to the groove structures and the protrusions. When the sidewalls of the groove structures contact the protrusions of the spindle 6, the driven plate and the spindle 6 are contact-limited.

[0096] The operating mechanism of this embodiment is the operating mechanism of a three-position switch. The flip member 3 is rotatably arranged and can be rotated to the first position of the flip member, the middle position of the flip member and the second position of the flip member. The first position of the flip member and the second position of the flip member are symmetrically arranged on both sides of the middle position of the flip member. The main shaft 6 can rotate between the main power closing position, the double open position and the backup power closing position; when the flip member 3 is in the middle position of the flip member, the main shaft 6 is in the double open position; when the flip member is in the first position of the flip member, the main shaft 6 is in the main power closing position; when the flip member is in the second position of the flip member, the main shaft 6 is in the backup power closing position.

[0097] When the flip member 3 rotates from the middle position of the flip member to the first position of the flip member, or from the first position of the flip member to the middle position of the flip member, the first connecting rod mechanism 12 is driven to drive the first energy storage spring 11 to first store energy and then release energy after crossing the equilibrium position (dead point position). The first energy storage spring 11 releases energy and drives the first connecting rod mechanism 12 to drive the main shaft 6 to rotate to the corresponding main power closing position or double-open position; when the flip member 3 rotates from the middle position of the flip member to the second position of the flip member, or from the second position of the flip member to the middle position of the flip member, the second connecting rod mechanism 22 is driven to drive the second energy storage spring 21 to first store energy and then release energy after crossing the equilibrium position (dead point position). The second energy storage spring 21 releases energy and drives the second connecting rod mechanism 22 to drive the main shaft 6 to rotate to the corresponding backup power closing position or double-open position.

[0098] The specific action process of the energy storage mechanism in this embodiment is as follows: Figure 2b 、 Figure 2c 、 Figure 3a 、 Figure 3b 、 Figure 4a 、 Figure 4b 、 Figure 4c 、 Figure 5a and Figure 5bAs shown, when the flip member 3 rotates from the middle position of the flip member to the first position of the flip member, or from the first position of the flip member to the middle position of the flip member, the first connecting rod shaft 123 is basically located at one end side wall of the first arc slot 31, and the flip member 3 drives the first connecting rod shaft 123 through the end side wall of the first arc slot 31, thereby driving the first driven plate 121 and the first pulling plate 122 to move. The first pulling plate 122 is forced to pull the first energy storage spring 11 to store energy. When the first energy storage spring 11 is in a balanced position, the energy storage is completed, wherein the balanced position is as shown in FIG. Figure 3b and Figure 5b As shown, the rotation axis of the first energy storage spring 11, the first driven plate 121 and the force direction of the first connecting rod shaft 123 are on the same straight line, and the forces are balanced. The forces of the first energy storage spring 11 and the first connecting rod shaft 123 are offset, and the flip member 3 continues to rotate counterclockwise under the force (as shown in FIG. Figure 3b ) or the flip member 3 continues to rotate clockwise (as Figure 5b ) drives the first driven plate 121 and the first pulling plate 122 to drive the first energy storage spring 11 to slightly pass the equilibrium position, and the flip member 3 reaches the first position of the flip member or the middle position of the flip member, and the driven plate driving part 1213 contacts the main shaft linkage part 61 to limit, and the energy of the first energy storage spring 11 is released. The first energy storage spring 11 pulls the first pulling plate 122, so that the first pulling plate 122 drives the first driven plate 121 to rotate through the first connecting rod shaft 123, and the first driven plate 121 drives the main shaft 6 to rotate to the corresponding main power closing position or double opening position through the driven plate driving part 1213, thereby realizing the state switching of the automatic transfer switch. After the first energy storage spring 11 releases energy, the first connecting rod shaft 123 slides from one end side wall of the first circular arc slot 31 to the other end of the first circular arc slot 31, and the flip member 3 does not rotate. During this process, the second connecting rod shaft 223 of the second connecting rod mechanism 22 slides in the second arcuate groove 32 of the flip member 3, sliding from one sidewall of the second arcuate groove 32 to the other sidewall, and the second connecting rod mechanism 22 does not move. The driven plate driving portion 1213 of the first driven plate 121 and the main shaft linkage portion 61 of the main shaft 6 can contact at the equilibrium position or after the first energy storage spring 11 releases energy.

[0099] like Figure 2b 、 Figure 2c 、 Figure 6a 、 Figure 6b 、 Figure 7a and Figure 8aAs shown, when the flip member 3 rotates from the middle position to the second position, or vice versa, the flip member 3 drives the second link mechanism 22 via the second arcuate slot 32 and the second connecting rod shaft 223. The operation process is similar to that of the first link mechanism 12 and the first energy storage spring 11 described above and will not be repeated here. During this process, the first connecting rod shaft 123 of the first connecting rod mechanism 12 slides in the first arcuate slot 31 of the flip member 3, and the first connecting rod mechanism 12 does not operate.

[0100] Preferably, the operating mechanism is provided with a first connecting rod limiting portion 1025 and a second connecting rod limiting portion, respectively used to limit the rotational position of the activated plate after the first and second energy storage mechanisms 1 and 2 release energy, thereby accurately and reliably limiting the rotational position of the main shaft 6. In this embodiment, the first and second connecting rod limiting portions 1025 and 1026 are disposed on the bracket 102. Of course, in other embodiments, the first and second connecting rod limiting portions 1025 and 1027 may not be provided, and the rotational position of the first and second activated plates 121 and 221 may be limited solely by the sidewalls at both ends of the first and second circular arc grooves 31 and 32 of the flip member 3.

The driven plate limiting portion 1216 and the driven plate connecting portion are respectively located on either side of the driven plate rotating portion. The first pulling plate 122 is a plate-shaped structure. Its first end is connected to the first energy storage spring 11, and its second end is connected to the first driven plate 121. A bend is formed between the first and second ends of the first pulling plate 122. In this embodiment, the bend creates a V- or U-shaped structure for the first pulling plate 122. This structure helps avoid the spindle 5 during the rotation of the first linkage 12, reduces the rotational distance between the first driven plate 121 and the first pulling plate 122, and reduces the space occupied. In other embodiments, the first pulling plate 122 may also be a straight structure, have other shapes, or have multiple bends.

Both the driven plates and the pulling plates can rotate about the connecting rod shaft. Preferably, a pulling plate limiting shaft 1215 is further provided between the two driven plates 1214 to limit the rotation angle of the pulling plate.
