[0044] The following is a further description of the specific implementation of the automatic transfer switch of the utility model in conjunction with the embodiments given in the accompanying drawings. The automatic transfer switch of the utility model is not limited to the description of the following embodiments.

[0045] like Figure 1-2 As shown, the automatic transfer switch of this embodiment includes a housing and an operating handle 11 and an electric operating device respectively arranged in the housing. The operating handle 11 is used to drive the trigger member 12 to rotate, and the electric operating device drives the trigger member 12 to rotate through the conversion member 13. In this embodiment, the conversion member 13 and the trigger member 12 are gears that mesh with each other. The trigger member 12 is used to trigger a first switch 14 that controls the normal power supply and the backup power supply. The normal power supply or the backup power supply controlled by the first switch 14 is powered off or powered on, so as to realize the conversion between the normal power supply and the backup power supply. The trigger member 12 is directly or indirectly connected to the moving contact, and the moving contact is driven to rotate by the trigger member 12, so that the moving contact is separated from one of the static contact of the normal power supply and the static contact of the backup power supply, and contacts with the other one. In addition, the operating handle 11 and the trigger 12 may not be provided, and a moving contact may be provided on the conversion member 13, or the conversion member 13 may indirectly drive the moving contact, and the conversion member 13 may drive the moving contact to contact with the static contact connected to the normal power supply, or to contact with the static contact connected to the backup power supply, and the electric operating device may directly control the conversion between the normal power supply and the backup power supply through the conversion member 13, which all belong to the protection scope of the present utility model. In addition, as other embodiments, the conversion member 13 and the trigger 12 may not be matched through gear transmission, but may be driven by a connecting rod, or a transmission groove may be provided in one of the conversion member 13 and the trigger 12, and a transmission protrusion may be provided in the other.

[0046] like Figure 1 Preferably, two first switches 14 are provided on both radial sides of the trigger member 12, and the two first switches 14 are respectively connected to the control circuit as auxiliary contacts, and are used to feedback the state of the automatic transfer switch, indicating whether the current power supply is the normal power supply or the backup power supply. In this embodiment, the first switch 14 is a micro switch, and a trigger protrusion is provided on the radial direction of the trigger member 12. When the trigger member 12 rotates to the normal power supply position, the trigger protrusion triggers one of the first switches 14, and when the trigger member 12 rotates to the backup power supply position, the trigger protrusion triggers the other first switch 14.

[0047] like Figure 3-5 As shown, the electric operation device of this embodiment includes an electromagnetic mechanism 2, a transmission shaft 3, an energy storage spring 4, a guide plate 8 and a guide mechanism. The transmission shaft 3 is used to drive the conversion member 13 to rotate to realize the conversion between the normal power supply and the backup power supply. The guide plate 8 is provided with a slide groove for inserting the transmission shaft 3. The electromagnetic mechanism 2 and the energy storage spring 4 are used to drive the transmission shaft 3 to move in the slide groove. The slide groove includes an intermediate slide groove 80 and a first slide groove 81 and a second slide groove 82 respectively connected to the intermediate slide groove 80. When the transmission shaft 3 moves to the first slide groove 81, the conversion member 13 is driven to supply power to the normal power supply and the backup power supply is cut off. When the transmission shaft 3 moves to the second slide groove 82, the conversion member 13 is driven to supply power to the backup power supply and the normal power supply is cut off.

[0048] The electromagnetic mechanism 2 is used to drive the transmission shaft 3 to move from the first slide groove 81 and the second slide groove 82 to the middle slide groove 80. When the electromagnetic mechanism 2 releases the transmission shaft 3, the energy storage spring 4 is used to drive the transmission shaft 3 to move from the middle slide groove 80 to the first slide groove 81 or the second slide groove 82. The guide mechanism plays a guiding role, so that the transmission shaft 3 can alternately enter the first slide groove 81 and the second slide groove 82, that is, after the transmission shaft 3 moves from the first slide groove 81 to the middle slide groove 80, the guide mechanism guides the transmission shaft 3 from the middle slide groove 80 to enter the second slide groove 82; after the transmission shaft 3 moves from the second slide groove 82 to the middle slide groove 80, the guide mechanism guides the transmission shaft 3 from the middle slide groove 80 to enter the first slide groove 81.

[0049] The guide mechanism is capable of moving between a first guide position and a second guide position. When the guide mechanism is located at the first guide position, it can guide the transmission shaft 3 from the middle slide groove 80 to the first slide groove 81. When the transmission shaft 3 moves to the first slide groove 81, the guide mechanism is driven to move from the first guide position to the second guide position. When the guide mechanism is located at the second guide position, it can guide the transmission shaft 3 from the middle slide groove 80 to the second slide groove 82. When the transmission shaft 3 moves to the second slide groove 82, the guide mechanism is driven to move from the second guide position to the first guide position.

[0050] When the automatic transfer switch switches the normal power supply and the backup power supply through the electric operation device, the electromagnetic mechanism 2 is controlled to operate, and the electromagnetic mechanism 2 drives the transmission shaft 3 to separate from the guide mechanism and enter the middle slide groove 80 and stores energy in the energy storage spring 4, and then the electromagnetic mechanism 2 is powered off to release the transmission shaft 3. When the electromagnetic mechanism 2 releases the transmission shaft 3, the energy storage spring 4 releases energy and drives the transmission shaft 3 to move quickly along the release direction close to the guide mechanism, and alternately enters the first slide groove 81 and the second slide groove 82 under the guidance of the guide mechanism.

[0051] The automatic switching switch of the present embodiment, through the cooperation of the electromagnetic mechanism 2, the energy storage spring 4 and the guide mechanism, only needs one set of the electromagnetic mechanism 2 and the energy storage spring 4 to control the transmission shaft 3 to realize the conversion between the normal power supply and the backup power supply, and does not need two sets of the electromagnetic mechanism 2 and the energy storage spring 4 to respectively control the transmission shaft 3 to realize the conversion between the normal power supply and the backup power supply, thereby reducing the number of the relatively large electromagnetic mechanisms 2, and also reducing the number of the energy storage springs 4, thereby reducing the volume and reducing the cost.

[0052] In this embodiment, the guide mechanism includes a rotatable guide member 5 and a transmission member 6, and an elastic mechanism 7 connected to the transmission member 6. When the transmission member 6 rotates, it can drive the guide member 5 to rotate. The transmission member 6 is provided with two transmission parts 61 relatively arranged on both sides of the rotation center. The guide member 5 is provided with two guide parts 51 for guiding the transmission shaft 3 into the first slide groove 81 and the second slide groove 82 respectively. The elastic mechanism 7 is used to drive the guide part 51 on one side to rotate to the release direction of the transmission shaft 3, so that the guide part 51 guides the transmission shaft 3 to push the corresponding transmission part 61; the transmission part 61 drives the elastic mechanism 7 to rotate under the push of the transmission shaft 3, so that the elastic mechanism 7 drives the other guide part 51 to rotate to the release direction of the transmission shaft 3, and is used to guide the transmission shaft 3 to push the transmission part 61 corresponding to the guide part 51 when the electromagnetic mechanism 2 releases the transmission shaft 3 next time. The conversion member 13 is used to control the power off of one of the normal power supply and the backup power supply and to supply power to the other under the push of the transmission shaft 3.

[0053] Specifically, when the guide mechanism is located at the first guide position, the guide portion 51 for guiding the transmission shaft 3 to enter the first slide groove 81 corresponds to the middle slide groove 80, and the elastic mechanism 7 acts on the transmission member 6 to make one transmission portion 61 of the transmission member 6 correspond to the first slide groove 81; when the guide mechanism is located at the second guide position, the other guide portion 51 for guiding the transmission shaft 3 to enter the second slide groove 82 corresponds to the middle slide groove 80, and the elastic mechanism 7 acts on the transmission member 6 to make another transmission portion 61 of the transmission member 6 correspond to the second slide groove 82;

[0054] When the transmission shaft 3 enters the first sliding groove 81, the transmission member 6 is driven to rotate through a transmission part 61, and the transmission member 6 drives the elastic mechanism 7 to store energy and release energy after crossing the zero position. The elastic mechanism 7 releases energy to drive the transmission member 6 to continue to rotate, and the transmission member 6 drives the guide member 5 to rotate, so that the guide mechanism switches from the first guide position to the second guide position;

[0055] When the transmission shaft 3 enters the second sliding groove 82, it drives the transmission member 6 to rotate in the opposite direction through another transmission part 61. The transmission member 6 drives the elastic mechanism 7 to store energy and release the energy after crossing the zero position. The elastic mechanism 7 releases the energy to drive the transmission member 6 to continue to rotate, and the transmission member 6 drives the guide member 5 to rotate in the opposite direction, so that the guide mechanism switches from the second guide position to the first guide position.

[0056] The automatic conversion switch of this embodiment controls the direction of an elastic mechanism 7 through a rotatable transmission member 6, so that the elastic mechanism 7 drives two guide parts 51 to guide the transmission shaft 3 respectively. After the electromagnetic mechanism 2 releases the transmission shaft 3 each time, the transmission shaft 3 can move along a guide part 51 different from the last release, thereby realizing alternating movement along the two directions of the normal power supply and the backup power supply respectively, and has the characteristics of a small number of parts, a simple structure and a small size.

[0057] In addition, by driving the trigger member 12 to rotate through the conversion member 13, and then driving the moving contact to rotate through the trigger member 12, the distance between the conversion member 13 and the rotation center of the trigger member 12 can be adjusted to adjust the rotation angle of the conversion member 13, especially the rotation angle of the conversion member 13 can be increased, thereby increasing the angle of the moving contact when it rotates. When the moving contact is away from the static contact of the common power supply and the static contact of the backup power supply, it can be moved to a farther position, thereby achieving the effect of increasing the opening distance. Figure 3-5 As shown, the electromagnetic mechanism 2 includes a pull rod 21 and a coil 22 for driving the pull rod 21 to move, a moving shaft 23 is provided on the pull rod 21, the moving shaft 23 is vertically arranged to the pull rod 21, two ends of the moving shaft 23 are relatively arranged on both sides of the pull rod 21, one end of the moving shaft 23 is connected to the transmission shaft 3 through a connecting rod 24, and the two ends of the connecting rod 24 are respectively rotatably connected to the moving shaft 23 and the transmission shaft 3, and the energy storage spring 4 is connected between the other end of the moving shaft 23 and the fixed shaft 25.

[0058] like Figure 2As shown, the guide mechanism includes a guide member 5 and a transmission member 6, both of which are rotatably arranged on a guide plate 8, and the transmission member 6 and the guide member 5 are driven to cooperate with each other, and the transmission member 6 can drive the guide member 5 to rotate when the transmission member 6 rotates, and the two ends of the elastic mechanism 7 are rotatably connected with the transmission member 6 and the guide plate 8 respectively, and one end of the elastic mechanism 7 rotatably connected with the guide plate 8 is the rotation center axis of the elastic mechanism 7, that is, the end of the elastic mechanism 7 away from the transmission member 6 serves as the rotation center axis of the elastic mechanism 7, and the elastic mechanism 7 is used to make the guide member 5 and the transmission member 6 located in the first guide position or the first guide position, and the plane where the rotation center axis of the elastic mechanism 7 and the rotation center axis of the transmission member 6 are located is the zero point position also called the dead point position;

[0059] When the transmission shaft 3 is driven by the energy storage spring 4 to push the transmission member 6 located at the first guide position to rotate, it can drive the elastic mechanism 7 to cross the zero position, so that the elastic mechanism 7 releases energy to push the transmission member 6 to rotate, and the transmission member 6 drives the guide member 5 to rotate to the second guide position; when the transmission shaft 3 is driven by the energy storage spring 4 to push the transmission member 6 located at the second guide position to rotate, it can drive the elastic mechanism 7 to cross the zero position, so that the elastic mechanism 7 drives the transmission member 6 to rotate, and the transmission member 6 drives the guide member 5 to rotate to the first guide position. When the transmission shaft 3 is driven by the electromagnetic mechanism 2 to leave the first slide groove 81 and the second slide groove 82, the transmission shaft 3 can also push the guide member 5 to drive the elastic mechanism 7 to rotate toward the zero position, but the elastic mechanism 7 can only be slightly rotated by the guide member 5, and the elastic mechanism 7 cannot reach the zero position. The transmission shaft 3 will separate from the guide member 5 before the elastic mechanism 7 reaches the zero position, and then the elastic mechanism 7 will reset and drive the transmission member 6 and the guide member 5 to reset.

[0060] Further, in this embodiment, the guide member 5 and the transmission member 6 are coaxially rotatably arranged, and when the transmission member 6 rotates, it can drive the guide member 5, so that the guide mechanism moves from the first guide position to the second guide position, or when it moves from the second guide position to the first guide position, the rotation angle of the transmission member 6 is greater than the rotation angle of the guide member 5. Of course, as other inferior embodiments, the guide member 5 and the transmission member 6 can also rotate synchronously without the need for an idle stroke of relative rotation; or, the guide member 5 and the transmission member 6 are integrally arranged.

[0061] like Figure 7In one embodiment shown, a transmission groove 63 for accommodating the guide member 5 is provided on one side of the transmission member 6, and the guide member 5 is arranged in the transmission groove 63. When the transmission member 6 rotates, the guide member 5 is driven to rotate through the side wall of the transmission groove 63. The size of the transmission groove 63 is larger than the size of the guide member 5, so that the transmission member 6 rotates a certain idle stroke before driving the guide member 5, and the rotation angle of the transmission member 6 is larger than the rotation angle of the guide member 5. In addition, as another embodiment, the guide member 5 and the transmission member 6 can also be elastically connected by an elastic member, and a protruding transmission column is provided on the transmission member 6, and a transmission column is provided on the guide member 5 to extend into a matching first transmission groove.

[0062] Further, when the electromagnetic mechanism 2 drives the transmission shaft 3 to separate from the guide mechanism, the transmission shaft 3 pushes the blocking portion 52 on the guide member 5 and drives the elastic mechanism 7 to rotate toward the zero position. Before the elastic mechanism 7 reaches the zero position, the transmission shaft 3 can be separated from the blocking portion 52, so that the elastic mechanism 7 is away from the zero position and drives the blocking portion 52 to reset. Preferably, a rotatable roller 31 is provided on the transmission shaft 3, and the roller 31 is slidably matched with the slide groove to reduce friction and avoid stagnation or jamming.

[0063] Specifically, the slide groove is in a Y-shape, and the slide groove includes an intermediate slide groove 80 and a first slide groove 81 and a second slide groove 82 respectively connected to the intermediate slide groove 80, and the first slide groove 81 and the second slide groove 82 are symmetrically arranged on both sides of the intermediate slide groove 80. The electromagnetic mechanism 2 is used to drive the transmission shaft 3 to move from the first slide groove 81 and the second slide groove 82 to the intermediate slide groove 80, and the first slide groove 81 and the second slide groove 82 are respectively arranged at one end away from the intermediate slide groove 80 corresponding to the two transmission parts 61, and the elastic mechanism 7 is used to drive the blocking part 52 to move between the side surfaces of the first slide groove 81 and the second slide groove 82, and the two guide parts 51 are relatively arranged on both sides of the blocking part 52 along the circumferential direction of the guide member 5, and the blocking part 52 can be rotated to the side of one of the first slide groove 81 and the second slide groove 82, so as to block the transmission shaft 3 from sliding in, and guide the transmission shaft 3 to slide through the guide part 51 located in the release direction. The guide member 5 is moved to the first position and the second position and the blocking member 52 is moved to the second position. The blocking member 52 is moved to the first position and the second position and the blocking member 52 is moved to the second position. The guide member 5 is moved to the first position and the second position and the blocking member 52 is moved to the second position. The guide member 5 is moved to the second position and the blocking member 52 is moved to the second position. The guide member 5 is moved to the second position and the blocking member 52 is moved to the first position and the second position.

[0064] The first slide groove 81 and the second slide groove 82 are relatively arranged on both sides of the axis of the conversion member 13. When the transmission shaft 3 slides into the first slide groove 81 and the second slide groove 82 respectively, it can push the conversion member 13 to rotate in opposite directions, thereby realizing the mutual conversion between the normal power supply and the standby power supply. When the transmission shaft 3 pushes the transmission part 61 to drive the transmission member 6 to rotate, the transmission member 6 can drive the elastic mechanism 7 to rotate from one side of the zero position to the other side, so that the elastic mechanism 7 pushes the transmission member 6 to continue to rotate in the opposite direction. When the guide mechanism is located at the first guide position, one of the transmission parts 61 is located on the side of the second slide groove 82, and the blocking part 52 is located on the side of the first slide groove 81, which is used to guide the transmission shaft 3 to slide into the second slide groove 82; when the guide mechanism is located at the second guide position, the other transmission part 61 is located on the side of the first slide groove 81, and the blocking part 52 is located on the side of the second slide groove 82, which is used to guide the transmission shaft 3 to slide into the first slide groove 81.

[0065] like Figure 10-12 The pull-in process shown is:

[0066] like Fig.10 As shown, as a result of the last release action, the guide mechanism is located at the first guide position, the transmission shaft 3 is located in the first slide groove 81, one of the transmission parts 61 is arranged corresponding to the second slide groove 82, and is used to guide the transmission shaft 3 to enter the second slide groove 82 next time, and the blocking part 52 is located on the side of the first slide groove 81, and is arranged corresponding to the first slide groove 81. The blocking part 52 is used to block the transmission shaft 3 to prevent the transmission shaft 3 from entering the first slide groove 81 when it is released next time. When the transmission shaft 3 leaves the first slide groove 81 under the attraction and drive of the electromagnetic mechanism 2, the transmission shaft 3 will push the blocking part 52 to rotate toward the second slide groove 82, as shown in FIG. Fig.11 As shown, the blocking portion 52 is limited by the elastic mechanism 7, and the elastic mechanism 7 will not reach the zero position before the transmission shaft 3 and the blocking portion 52 are separated. Fig.12 As shown, after the transmission shaft 3 is separated from the blocking portion 52, the elastic mechanism 7 drives the guide member 5 and the transmission member 6 to return to the first guiding position, and the blocking portion 52 returns to the first slide groove 81, which is used to prevent the transmission shaft 3 from sliding into the first slide groove 81 where the blocking portion 52 is located after the transmission shaft 3 is released next time, and the guide portion 51 on the blocking portion 52 facing the second slide groove 82 also returns to the first guiding position.

[0067] Figure 13-15 The specific release process shown is:

[0068] like Fig.13 As shown, when the coil 22 of the electromagnetic mechanism 2 loses power when the attraction reaches the maximum point, the transmission shaft 3 is released. After the electromagnetic mechanism 2 is released, the energy storage spring 4 drives the transmission shaft 3 to move along the release direction, as shown in FIG. Fig.14 As shown, since the blocking portion 52 is located on the side of the first slide groove 81, and one of the guide portions 51 is located in the release direction, the transmission shaft 3 slides into the second slide groove 82 under the guidance of the guide portion 51. As a result of the last release action, the transmission shaft 3 pushes the transmission portion 61 on the side of the first slide groove 81, so that the elastic mechanism 7 drives the transmission portion 61 of the second slide groove 82 to rotate to the side of the second slide groove 82. When the transmission shaft 3 slides into the second slide groove 82, it will push the transmission portion 61 on the side of the second slide groove 82 to drive the transmission member 6 to rotate, drive the elastic mechanism 7 to cross the zero position, and at the same time push the conversion member 13 to control the switching between the normal power supply and the backup power supply. After driving the elastic mechanism 7 to cross the zero position, it drives the transmission member 6 and the guide member 5 to rotate to Fig.15 position, so that the blocking part 52 of the guide member 5 moves to the second slide groove 82, so that the other guiding part 51 on the blocking part 52 moves to the release direction of the transmission shaft 3, and the other transmission part 61 moves to the side of the first slide groove 81, and the guiding mechanism moves to the second guiding position.

[0069] The engagement and release processes of manual and electric operations in this embodiment are substantially the same, with the difference being that during the engagement process, the operating handle 11 replaces the electromagnetic mechanism to drive the transmission shaft 3 to move to the middle slide groove, which will not be described in detail here.
