Description

Technical Field

[0001] The invention relates to a stop mechanism which is used for a moving contact driving disk of a dual power conversion switch; the invention also relates to a dual power conversion switch comprising the stop mechanism. Background Art

[0002] The dual power transfer switch (ATS) needs to switch between two different power sources to ensure the power supply continuity of the load. ATS is divided into two positions and three positions. The ATS with three positions, namely, the first power closing position, the double opening position and the second power closing position, wherein the double opening position is also called the OFF position, at which the load is not connected to the first power source and the second power source. For the ATS with isolation function, when the ATS product is in the double opening position, the user can padlock and repair the related equipment. Therefore, the isolation performance of the double opening position has become an important market demand. However, in the three-position ATS of the prior art, when the ATS needs to switch from the first power closing position or the second power closing position to the double opening position, the moving contact and the rotating parts associated with the moving contact often cannot stop quickly and reliably in the double opening position due to the large rotational inertia, and there is even a potential risk of connecting another power source, which is not conducive to the isolation performance of the dual power transfer switch.

[0003] Therefore, a stop mechanism is needed that can quickly and reliably stop the moving contact and the rotating parts associated with it at the double-open position when the ATS is intended to be switched from the first power-on position or the second power-on position to the double-open position. Summary of the invention

[0004] To this end, a first aspect of the present invention provides a stop mechanism, which is used for a moving contact drive disk of a dual power transfer switch (ATS), wherein the moving contact drive disk is fixedly connected to the moving contact and can rotate around a rotation axis, so that the moving contact can be in a first closing position, a second closing position, and a double opening position for opening, and wherein the moving contact drive disk includes a radially extending stop convex portion, the stop convex portion includes a first limiting portion and a second limiting portion that are circumferentially consecutive, and the stop mechanism includes:

[0005] A frame, which is arranged below the moving contact driving disk and can move up and down in the vertical direction;

[0006] A first baffle, which is mounted on a first side of the frame and is configured to cooperate with the first limiting portion so as to be able to rotate only in a first direction from its first initial position;

[0007] a second baffle plate mounted on a second side of the frame opposite to the first side and configured to cooperate with the second limiting portion so as to be able to rotate from its second initial position only in a second direction opposite to the first direction;

[0008] A first reset member, disposed between the first baffle plate and the second baffle plate;

[0009] Wherein, the stop mechanism is constructed such that:

[0010] As the moving contact driving disk rotates from the first closing position to the double opening position along the second direction, the first baffle plate can rotate from the first initial position along the first direction. When the second limiting portion abuts against the second baffle plate, the moving contact driving disk stops rotating, and at the same time, the first reset member pulls the first baffle plate back to the first initial position, so that the stopping protrusion of the moving contact driving disk is located between the first baffle plate and the second baffle plate.

[0011] As the moving contact driving disk rotates from the second closing position to the double opening position along the first direction, the second baffle plate can rotate from the second initial position along the second direction. When the first limiting portion abuts against the first baffle plate, the moving contact driving disk stops rotating, and at the same time, the first reset member pulls the second baffle plate back to the second initial position, so that the stopping protrusion of the moving contact driving disk is located between the first baffle plate and the second baffle plate.

[0012] As the moving contact driving disk rotates from the double-open position to the first closing position or the second closing position, the frame moves downward, so that the first baffle plate and the second baffle plate no longer block the rotation of the moving contact driving disk.

[0013] That is, the stop mechanism according to the present invention ensures that the moving contact driving disk can be reliably stuck between the first baffle plate and the second baffle plate when it rotates from the first closing position or the second closing position to the double opening position through the cooperation of the first baffle plate and the second baffle plate that can only rotate in one direction from the corresponding initial position and the stop convex part of the moving contact driving disk and the first reset member, and ensures that the moving contact driving disk is no longer constrained by the first baffle plate and the second baffle plate when it rotates from the double opening position to the first closing position or the second closing position through the frame that can move up and down. It can be seen that the stop mechanism according to the present invention has a simple structure, is compact and stable, is easy to implement, and can reliably ensure the stopping effect on the moving contact driving disk when needed without interfering with the normal operation of the dual power conversion switch in other time periods.

[0014] In a more specific embodiment of the stop mechanism according to the present invention, the rotation of the first baffle along the first direction is driven by the stop convex portion, and / or the rotation of the second baffle along the second direction is driven by the stop convex portion. Thus, the rotation of the first baffle and the second baffle is achieved only by means of the rotational movement of the moving contact driving disk itself, without the need for other power application and transmission components, so that the number of components of the stop mechanism can be reduced, which is more conducive to realizing a compact structure of the stop mechanism.

[0015] In one embodiment of the stop mechanism according to the present invention, the frame includes a first shaft and a second shaft which are parallel to the rotation axis and spaced apart from each other and fixed to the frame, and includes a first stop portion and a second stop portion respectively arranged below the first shaft and the second shaft; the first baffle includes a first hole arranged in the middle section and a first corresponding limit portion and a first corresponding stop portion respectively arranged on both sides of the first hole, the first shaft passes through the first hole, and the first baffle cooperates with the first limit portion through the first corresponding limit portion, and the first corresponding stop portion is used to cooperate with the first stop portion; and / or the second baffle includes a second hole arranged in the middle section and a second corresponding limit portion and a second corresponding stop portion respectively arranged on both sides of the second hole, the second shaft passes through the second hole, and the second baffle cooperates with the second limit portion through the second corresponding limit portion, and the second corresponding stop portion is used to cooperate with the second stop portion. Such a first baffle and a second baffle have simple structures, and the shaft-hole matching structure makes the stop mechanism easy to assemble, that is, a quick and reliable stop of the moving contact drive disk is achieved with a simple structure, and the cost-effectiveness is high.

[0016] In a more specific embodiment of the stopping mechanism according to the present invention, the first stopping portion and the second stopping portion are arranged on opposite sides of the bottom of the frame.

[0017] In a more specific embodiment of the stop mechanism according to the present invention, the first baffle can be constructed as follows: the first corresponding limit portion is arranged on the first vertical segment of the first baffle, the first corresponding stop portion is arranged on the second vertical segment of the baffle, the first vertical segment and the second vertical segment are connected by a first transverse segment, and the first hole is arranged in a protrusion extending from the first vertical segment parallel to the first transverse segment; and / or the second baffle is constructed as follows: the first corresponding stop portion is arranged on the third vertical segment of the second baffle, the second corresponding stop portion is arranged on the fourth vertical segment of the second baffle, the third vertical segment and the fourth vertical segment are connected by a second transverse segment, and the fourth hole is arranged in a protrusion extending from the third vertical segment parallel to the second transverse segment. The construction of the first baffle and the second baffle, on the one hand, further ensures a reliable and stable stop effect in the double-open position, and on the other hand, ensures smooth rotation of the first baffle and the second baffle when it is necessary to switch from the first closing position or the second closing position to the double-open position, and is easy to manufacture and assemble.

[0018] In a more specific embodiment of the stop mechanism according to the present invention, each of the protrusions is composed of two parallel protrusions, which can save materials and make the first baffle and the second baffle lighter, thereby ensuring smoother rotation of the first baffle and the second baffle.

[0019] In a more specific embodiment of the stop mechanism according to the present invention, the first reset member is a first spring, which further ensures that the stop mechanism has a compact structure, is simple and reliable.

[0020] In an embodiment of the stopping mechanism according to the present invention, the stopping mechanism comprises a driving mechanism connected to the frame, and the driving mechanism drives the frame to move downward in a vertical direction.

[0021] In a more specific embodiment of the stop mechanism according to the present invention:

[0022] The dual power conversion switch further comprises an electromagnet rotating disk for driving the moving contact driving disk to rotate, wherein the electromagnet rotating disk comprises a third stopper and a fourth stopper which are circumferentially consecutive;

[0023] The first baffle and the second baffle are disposed near a third side of the frame, and the frame further comprises a first driving ramp and a second driving ramp rising toward each other and fixedly coupled to the frame near a fourth side opposite to the third side;

[0024] The driving mechanism comprises:

[0025] a first driving arm mounted on the electromagnet turntable to cooperate with the third stop portion so as to be able to rotate only in the second direction from a third initial position relative to the electromagnet turntable, and the first driving arm is further configured to cooperate with at least the first driving ramp;

[0026] a second driving arm mounted on the electromagnet turntable to cooperate with the fourth stop portion so as to be able to rotate only in the first direction from a fourth initial position relative to the electromagnet turntable, and the second driving arm is further configured to cooperate with at least the second driving ramp;

[0027] a second reset member, disposed between the first driving arm and the second driving arm;

[0028] Wherein, the driving mechanism is constructed as follows:

[0029] As the electromagnet rotary disk drives the moving contact driving disk to rotate from the first closing position to the double opening position along the second direction, the second driving arm can rotate relative to the electromagnet rotary disk from the fourth initial position along the first direction when contacting the first driving ramp and / or the second driving ramp, so that the second driving arm can slide over the first driving ramp and / or the second driving ramp, and when the moving contact driving disk reaches the double opening position, the second reset member returns the second driving arm to the fourth initial position;

[0030] As the electromagnet rotary disk drives the moving contact driving disk to rotate from the double-open position to the first closing position along the first direction, the second driving arm contacts the second driving ramp and thus applies pressure to the second driving ramp, so that the frame moves downward;

[0031] As the electromagnet rotary disk drives the moving contact driving disk to rotate from the second closing position to the double opening position along the first direction, the first driving arm can rotate relative to the electromagnet rotary disk from the third initial position along the second direction when contacting the second driving ramp and / or the first driving ramp, so that the first driving arm can slide over the second driving ramp and / or the first driving ramp, and when the moving contact driving disk reaches the double opening position, the second reset member causes the first driving arm to return to the third initial position;

[0032] As the electromagnet rotary disk drives the moving contact driving disk to rotate from the double-open position to the second closing position along the second direction, the first driving arm contacts the first driving ramp and thus applies pressure to the first driving ramp, causing the frame to move downward.

[0033] That is, in this embodiment, the driving mechanism for driving the frame to move downward when needed has a small number of components and a simple structure. What is more prominent is that the driving mechanism not only utilizes the electromagnet turntable that is usually included in the dual power conversion switch in terms of structure, but also utilizes the driving function of the electromagnet turntable itself in terms of power transmission. On the one hand, this makes full use of the limited space in the dual power conversion switch, so that the setting of the driving mechanism does not occupy more space. On the other hand, it saves the power source and control components for the driving mechanism, and the cost-effectiveness is very high. At the same time, such a first driving arm and the driving function of the first driving arm can be perfectly coordinated with the stopping function of the first baffle and the second baffle, so that the entire stopping mechanism has a compact structure, smooth operation, quick response, and is stable and reliable.

[0034] In a more specific embodiment of the stop mechanism according to the present invention, the first drive arm includes a third hole arranged in the middle section and a third corresponding stop portion and a first drive portion respectively arranged on both sides of the third hole, the third shaft fixed on the electromagnet turntable passes through the third hole, and the first drive arm cooperates with the third stop portion through the third corresponding stop portion, and cooperates with at least the first drive slope through the first drive portion; and / or the second drive arm includes a fourth hole arranged in the middle section and a fourth corresponding stop portion and a second drive portion respectively arranged on both sides of the fourth hole, the fourth shaft fixed on the electromagnet turntable passes through the fourth hole, and the second drive arm cooperates with the fourth stop portion through the fourth corresponding stop portion, and cooperates with at least the second drive slope through the second drive portion. Such a first drive arm and a second drive arm have a simple structure, and the shaft-hole matching structure makes the drive mechanism easy to assemble, that is, with a simple structure, the frame of the stop mechanism is effectively driven when the dual power conversion switch is from the first closing position or the second closing position to the double opening position, and the normal operation of the dual power conversion switch is not affected during other operations. In a more specific embodiment of the stop mechanism according to the present invention, the second reset member is a second spring, which further ensures a compact structure of the drive mechanism, and is simple and reliable.

[0035] In a more specific embodiment of the stop mechanism according to the present invention, the third corresponding stop portion of the first driving arm forms an obtuse angle with the first driving portion, the fourth corresponding stop portion of the second driving arm forms an obtuse angle with the second driving portion, and the first driving portion and the second driving portion extend parallel to the movement direction of the frame when in the double open position. Such a structure ensures that the first driving arm or the second driving arm is more firmly stopped when the dual power conversion switch moves from the double open position to the first closing position or the second closing position, and applies driving force to the frame in a more effective manner.

[0036] In a more specific embodiment of the stop mechanism according to the present invention, the third hole of the first drive arm is arranged in the first material thickening portion, and the fourth hole of the second drive arm is arranged in the second material thickening portion, thereby enhancing the mechanical strength of the first drive arm and the second drive arm.

[0037] In a more specific embodiment of the stop mechanism according to the present invention, the driving mechanism comprises at least one third reset member arranged in the vertical direction and connected to the frame, and the third reset member is arranged to reset the frame after being pressed down. Thus, the frame can be reset without external force.

[0038] In a more specific embodiment of the stop mechanism according to the present invention, the third reset member is arranged on a support shaft positioned in the vertical direction and connected to the frame, and the stop mechanism is installed in a bracket fixed to the dual power conversion switch through the support shaft. That is, the installation of the third reset member does not occupy more space, thereby further ensuring the compactness of the stop mechanism; at the same time, this can effectively ensure the upward and downward mobility of the frame.

[0039] In a more specific embodiment of the stop mechanism according to the present invention, the third reset member is a compression spring, which further ensures a compact structure of the drive mechanism, and is simple, reliable and easy to implement.

[0040] In a more specific embodiment of the stop mechanism according to the present invention, the first driving ramp and the second driving ramp are integrally arranged on the frame, thereby reducing the number of components of the stop mechanism, saving assembly costs, and ensuring that the driving force is effectively transmitted to the frame.

[0041] In a more specific embodiment of the stop mechanism according to the present invention, the first driving ramp and the second driving ramp are respectively arranged on a first driving side surface and a second driving side surface extending upward from the bottom of the frame.

[0042] In a more specific embodiment of the stop mechanism according to the present invention, the frame further comprises a side surface arranged on the third side and extending from the bottom, the first shaft is mounted in the side surface and the first driving side surface, and the second shaft is mounted in the side surface and the second driving side surface. Such an arrangement facilitates the installation of the first shaft and the second shaft, and further ensures the compactness of the structure of the stop mechanism.

[0043] In a more specific embodiment of the stop mechanism according to the present invention, it is characterized in that a pin for connecting the moving contact is arranged in the stop protrusion of the moving contact driving disk, thereby ensuring that the moving contact is kept in the double open position more accurately.

[0044] According to the second invention of the present invention, the present invention provides a dual power conversion switch, which includes the stop mechanism as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0124] like Figures 1 to 5 As shown, it shows a three-dimensional view and an exploded three-dimensional view of a dual power conversion switch 1 including a stop mechanism 10 according to an embodiment of the present invention. As shown in the figure, the dual power conversion switch 1 according to the present invention at least includes: an electromagnet turntable 20, a moving contact drive disk 40, a moving contact (not shown), one or more support plates and a turntable shaft 90 and other multiple components. Three support plates are shown in the figure, namely the first support plate 31, the second support plate 62 and the third support plate 63. The electromagnet turntable 20 and the moving contact drive disk 40 are installed on the turntable shaft 90 (in Figure 2 The moving contact is connected to the moving contact drive disk 40 by a pin 41 (in Figure 2 The electromagnet turntable 20 is fixedly connected to the moving contact drive disk 40. When subjected to external force, the electromagnet turntable 20 can rotate around the rotation axis X on the turntable shaft 90, and can drive the moving contact drive disk 40 to rotate around the rotation axis X on the turntable shaft 90. The moving contact drive disk 40 can drive the moving contact to switch to the first closing position ( Fig.14 shown), the second closing position (not shown) and the double opening position ( Figure 2-5 and Figure 10-11 As shown in Figure 1-2 As shown, the dual power conversion switch 1 optionally includes a gear plate 70 disposed between the electromagnet rotating disk 20 and the moving contact driving disk 40, so that the electromagnet rotating disk 20 drives the moving contact driving disk 40 via the gear plate 70. Also optionally, there may be a delay between the rotation of the electromagnet rotating disk 40 and the rotation of the moving contact driving disk 20 due to an energy storage spring (not shown) matched with the electromagnet rotating disk 40. One or more support plates 61, 62, 63 are configured to support other components.

[0125] like Figure 1-5 As shown, in order to ensure that the moving contact and the moving contact drive disk 40 fixedly connected thereto are quickly and reliably stopped at the double-open position when the dual power conversion switch 1 is switched from the first closing position or the second closing position to the double-open position, and will not continue to rotate due to the rotational inertia, a stop mechanism 10 for the moving contact drive disk 40 of the dual power conversion switch 1 is proposed. As shown in the figure, according to one embodiment, in order to cooperate with the stop mechanism 10 to stop the moving contact drive disk 40 at the double-open position, the moving contact drive disk 40 includes a stop protrusion 42 extending radially outward, and a first limit portion 421 and a second limit portion 422 are successively arranged circumferentially on the stop protrusion 42, as shown in FIG. Figure 3 As shown, the first limit portion 421 and the second limit portion 422 are, for example, arranged in a symmetrical manner relative to the stop convex portion 42. In addition, the pin 41 for fixedly mounting the moving contact is, for example, arranged in the stop convex portion 42. The stop mechanism 10 includes a first baffle 100 and a second baffle 200 that can clamp the stop convex portion of the moving contact driving disk in the middle at the double-open position, and when the dual power conversion switch 1 intends to switch from the double-open position to the first closing position or the second closing position, the first baffle 100 and the second baffle 200 can move downward to release the constraint on the stop convex portion 42.

[0126] To this end, as shown in the figure, the stop mechanism 10 includes a frame 300, a first baffle 100 and a second baffle 200, wherein the frame 300 is arranged below the moving contact driving disk 40 and can move up and down in the vertical direction, and the first baffle 100 is installed on the first side 351 of the frame 300 and is arranged to be able to cooperate with the first limiting portion 421 on the stop protrusion 42 of the moving contact driving disk 40 so that the moving contact can only move in the first direction ( Figure 3 and Figure 6-7 The second baffle plate 200 is, for example, mounted on the second side 352 of the frame 300 in a symmetrical manner to the first baffle plate 100 and is configured to cooperate with the second stopper 422 of the stopper protrusion 42 of the moving contact driving disk 40 so as to be able to move from its second initial position only in a second direction ( Figure 3 and Figure 6-7 In addition, as shown in the figure, the stop mechanism 10 further includes a first reset member 150 disposed between the first baffle 100 and the second baffle 200, and the first reset member 150 is, for example, a spring. The stop mechanism 10 according to the present invention is configured as follows:

[0127] like Figure 14-17 As shown, when the moving contact drive disc moves from Fig.14 The first closing position shown is along the second direction ( Fig.14 , 16 and 17 are counterclockwise, Fig.15 (clockwise direction as shown in the figure) to Figure 10-11 When the first baffle plate 100 is in the double split position, it moves from the first initial position along the first direction ( Fig.16 As shown in FIG. 1 , the second contact driving disk 40 rotates clockwise, and when the second stopper 422 on the stopper protrusion 42 of the moving contact driving disk 40 abuts against the second baffle 200 ( Fig.17 As shown in FIG. 1 , since the second baffle 200 cannot be moved in the first direction, i.e. Fig.17 The moving contact driving disk 40 is rotated clockwise, so that the moving contact driving disk 40 is stopped, and at the same time, the first reset member 150 drives the first baffle 100 back to the first initial position, so that the stop convex portion 42 of the moving contact driving disk 40 is limited between the first baffle 100 and the second baffle 200 (such as Fig.17 and Fig.10 In a specific embodiment, as shown Fig.16 As shown, the rotation of the first baffle 100 in the first direction is driven by the stop convex portion 42 of the moving contact driving disk 40, that is, during the above rotation process of the moving contact driving disk 40, the stop convex portion 42 will touch the first baffle 100 and apply a force to the first baffle 100 in the first direction to make the first baffle 100 rotate in the first direction;

[0128] Correspondingly, when the moving contact driving disk 40 rotates from the second closing position to the double opening position along the first direction, the second baffle 200 rotates from the second initial position along the second direction. When the first limiting portion 421 on the stopping protrusion 42 of the moving contact driving disk 40 abuts against the first baffle 100, since the first baffle 100 cannot rotate along the second direction, the moving contact driving disk 40 stops rotating. At the same time, the first reset member 150 drives the second baffle 200 back to the second initial position, so that the stopping protrusion 42 of the moving contact driving disk 40 is limited between the first baffle 100 and the second baffle 200. In a specific embodiment, the rotation of the second baffle 200 in the second direction is driven by the stopping protrusion 42 of the moving contact driving disk 40, that is, during the above-mentioned rotation process, the stopping protrusion 42 of the moving contact driving disk 40 will touch the second baffle 200 and apply force to the second baffle 200 in the second direction to rotate the second baffle 200 in the second direction (not shown).

[0129] In addition, if Figures 10 to 14 As shown, when the moving contact driving disk 40 rotates from the double-open position to the first closing position or the second closing position, the frame 300 moves downward (as shown in FIG. Fig.12 As shown), the stop protrusion 42 is free from the restriction of the first baffle 100 and the second baffle 200 (as shown Fig.13 As shown), the first baffle 100 and the second baffle 200 no longer block the rotation of the moving contact driving disk 40.

[0130] Therefore, the stop mechanism 10 according to the present invention ensures that the moving contact drive disk 40 can be reliably stuck between the first baffle 100 and the second baffle 200 when it rotates from the first closing position or the second closing position to the double opening position through the cooperation of the first baffle 100 and the second baffle 200 that can only rotate in one direction from the corresponding initial position and the stop convex portion 42 of the moving contact drive disk 40 and the first reset member 150, and ensures that the moving contact drive disk 40 is no longer constrained by the first baffle 100 and the second baffle 200 when it rotates from the double opening position to the first closing position or the second closing position through the frame 300 that can move up and down. Therefore, the stop mechanism 10 according to the present invention can reliably ensure the stopping effect on the moving contact drive disk 40 when necessary without affecting the normal operation of the dual power conversion switch 1 in other time periods. In addition, the rotation of the first baffle 100 and the second baffle 200 can be achieved only by the rotational movement of the moving contact driving disk 40 itself, without the need for other power application and transmission components, so that the number of components of the stop mechanism 10 can be reduced, which is more conducive to achieving a compact structure of the stop mechanism 10 and is highly cost-effective.

[0131] In order to easily implement the stop mechanism of the present invention with a simple, compact and stable structure, in a specific embodiment, as Figure 4-8 As shown, the frame 300 includes a first shaft 303 and a second shaft 313 which are fixed to the frame 300 in parallel with the rotation axis X and spaced apart from each other, and includes a first stopper 301 and a second stopper 302 which are respectively arranged below the first shaft 303 and the second shaft 313 ( Figure 8 As shown in FIG. 3 , for example, the first shaft 303 and the second shaft 313 may be fixed on opposite sides of the frame 300, and the first stopper 301 and the second stopper 302 may be disposed on opposite sides 311 and 312 of the bottom 310 of the frame 300. Figure 8 , 10 As shown more clearly, the first baffle 100 includes a first hole 103 arranged in the middle section thereof and a first corresponding limiting portion 111 and a first corresponding stopping portion 121 respectively arranged on both sides of the first hole 103. The first shaft 303 fixed on the frame 300 passes through the first hole 103, and the first baffle 100 cooperates with the first limiting portion 421 on the stopping protrusion 42 of the moving contact driving disk 40 through the first corresponding limiting portion 111, and the first corresponding stopping portion 121 is used to cooperate with the first stopping portion 301 on the frame 300; similarly, the second baffle 200 includes a second hole 203 arranged in the middle section thereof and a second corresponding limiting portion 212 and a second corresponding stopping portion 222 respectively arranged on both sides of the second hole. The second shaft 313 fixed on the frame 300 passes through the second hole 203, and the second baffle 200 cooperates with the second limiting portion 422 on the stopping protrusion 42 of the moving contact driving disk 40 through the second corresponding limiting portion 212, and the second corresponding stopping portion 212 is used to cooperate with the second stopping portion 302 on the frame 300. That is, when the first baffle 100 is installed on the first shaft 303 of the frame 300 through its first hole 103, the first corresponding stopping portion 121 of the first baffle 100 can abut against the first stopping portion 301 on the frame 300, and the first baffle 100 is in its first initial position; similarly, when the second baffle 200 is installed on the second shaft 313 of the frame 300 through its second hole 203, the second corresponding stopping portion 222 of the second baffle 200 can abut against the second stopping portion 302 on the frame 300, and the second baffle 200 is in its second initial position, as shown in FIG. Fig.10 shown.

[0132] In this case, the stop mechanism 10 is specifically configured to operate as follows:

[0133] like Figure 14-17 As shown, when the moving contact driving disk 40 is Fig.14 The first closing position shown is along the second direction ( Fig.14 , 16 and 17 are counterclockwise, Fig.15 (clockwise as shown in the figure) to Fig.10 and 11 During the double-open position shown in FIG. 16 , the second limiting portion 422 side of the stop protrusion 42 of the moving contact driving disk 40 first contacts the outer side of the first corresponding limiting portion 111 of the first baffle 100, thereby applying a driving force to the first baffle 100, so that the first baffle 100 can be moved from its first initial position as shown in FIG. Fig.16 As shown in the figure, the stopper 42 is rotated in the clockwise direction, thereby enabling the stopper 42 to enter the space between the first baffle 100 and the second baffle 200; and when the second limiting portion 422 of the stopper 42 abuts against the second corresponding limiting portion 212 of the second baffle 200 (as shown in the figure), ... Fig.17 As shown in FIG. 1 , the second baffle plate 200 cannot move along the second stopper 302 of the frame 300 due to the cooperation between the second corresponding stopper 222 and the second stopper 302 of the frame 300. Fig.17 The moving contact driving disk 40 is rotated clockwise as shown in the figure, so that the moving contact driving disk 40 stops rotating, that is, its rotational inertia becomes zero, and the rotation of the moving contact fixedly connected thereto is also stopped accordingly. At the same time, the first reset member 150 drives the first baffle 100 back to the first initial position, so that the stop convex portion 42 of the moving contact driving disk 40 is located between the first baffle 100 and the second baffle 200, and thus the moving contact driving disk 40 and the moving contact are kept in the double-open position;

[0134] Correspondingly, when the moving contact driving disk 40 rotates from the second closing position to the double opening position along the first direction, the first limiting portion 421 side of the stop protrusion 42 of the moving contact driving disk 40 first contacts the outer side of the second corresponding limiting portion 212 of the second baffle 200, and thus applies a driving force to the second baffle 200, so that the second baffle 200 can rotate from its second initial position along the second direction, thereby enabling the stop protrusion 42 to enter the space between the second baffle 200 and the first baffle 100; and when the first limiting portion 421 of the stop protrusion 42 abuts against the first corresponding limiting portion 111 of the first baffle 100, the first baffle 100 cannot rotate along the second direction due to the cooperation between its first corresponding stopping portion 121 and the first stopping portion 301 on the frame 300, so that the moving contact driving disk 40 is stopped from rotating, that is, its rotational inertia becomes zero, and the rotation of the moving contact fixedly connected thereto is also stopped. At the same time, The first reset member 150 drives the second baffle plate 200 back to the second initial position, so that the stop protrusion 42 of the movable contact driving disk 40 is located between the first baffle plate 100 and the second baffle plate 200, and thus the movable contact driving disk 40 and thus the movable contact are kept in the double-open position (not shown);

[0135] like Figures 10 to 14 As shown, when the moving contact driving disk 40 is Figure 10-11 Turn the double split position shown to Fig.14 During the first closing position shown, the frame 300 moves downward ( Fig.12 ), so that the first baffle 100 and the second baffle 200 move down accordingly, so that the stop protrusion 42 of the moving contact driving disk 40 is separated from the space between the first baffle 100 and the second baffle 200, so that its rotation is no longer blocked (Figures 13 and 14). It should be noted that this process is also applicable when the moving contact driving disk 40 rotates from the double-open position to the second closing position.

[0136] Therefore, the first baffle plate and the second baffle plate have simple structures, and the shaft hole matching structure makes the stop mechanism easy to assemble, that is, the moving contact drive disk can be quickly and reliably stopped with a simple structure, which is cost-effective.

[0137] In a more specific embodiment, Figure 8 As shown, the first baffle 100 is constructed to have a first vertical segment and a second vertical segment, and the first vertical segment is connected to the second vertical segment through a first transverse segment 170. In this case, the first corresponding limiting portion 111 is arranged on the first vertical segment, the first corresponding stopping portion 121 is arranged on the second vertical segment, and the first hole 103 is arranged in a protrusion extending from the first vertical segment parallel to the first transverse segment 170. As shown in the figure, the protrusion is composed of two protrusions 141 and 142, for example. Similarly, the second baffle 200 may be configured to have a third vertical segment and a fourth vertical segment, and the third vertical segment and the fourth vertical segment are connected by a second transverse segment 270. In this case, the second corresponding limiting portion 212 is provided on the third vertical segment, the second corresponding stop portion 222 is provided on the fourth vertical segment, and the second hole 203 is provided in a protrusion extending from the third vertical segment parallel to the second transverse segment 270. As shown in the figure, the protrusion is composed of two protrusions 241 and 242, which can save materials, make the first baffle 100 and the second baffle 200 lighter, and ensure smoother rotation of the first baffle 100 and the second baffle 200. Of course, the first hole 103 and the second hole 203 may not be provided in the protrusion.

[0138] It should be noted that the construction, arrangement and installation of the above-mentioned first shaft, second shaft, first baffle, second baffle, first hole and second hole are exemplary, and other constructions and installation methods are also feasible, as long as the first baffle and the second baffle can be given the stopping effect as described above.

[0139] In a specific implementation of the stop mechanism according to the present invention, the up and down movement of the frame 300 of the stop mechanism 10 is achieved by a driving mechanism included in the stop mechanism 10 .

[0140] For this reason, Figure 4-5 and Figure 11-12As shown, the electromagnet turntable 20 of the dual power conversion switch 1 may include a third stopper 201 and a fourth stopper 211 which are arranged successively in the circumferential direction, for example, Figure 4-5 As shown, the third stopper 201 and the fourth stopper 211 are arranged on an axial surface in a manner protruding relative to an axial surface of the electromagnet turntable 20, and more specifically, the third stopper 201 and the fourth stopper 211 are arranged on the same protrusion protruding from the axial surface. Figure 8 As shown, the first baffle 100 and the second baffle 200 are arranged near the third side 353 of the frame 300 of the stop mechanism 10, and the frame 300 also includes a first driving ramp 321 and a second driving ramp 331 rising toward each other and fixedly connected to the frame 300 near the fourth side 354 opposite to the third side 353. For example, the first driving ramp 321 and the second driving ramp 322 are integrally arranged on the frame 300, and optionally, the first driving ramp 321 is arranged on the first driving side 320 extending upward from the bottom 310 of the frame 300, and the second driving ramp 331 is arranged on the second driving side 330 extending upward from the bottom 310 of the frame 300. According to one embodiment, the driving mechanism includes: a first driving arm 400, which is installed on the electromagnet turntable 20 to be able to cooperate with the third stop portion 201 so that it can only rotate in the second direction from its third initial position relative to the electromagnet turntable 20, and the first driving arm 400 is also configured to be able to cooperate with at least the first driving ramp 321; a second driving arm 500, which is installed on the electromagnet turntable 20, for example, in a symmetrical manner with the first driving arm 400, to be able to cooperate with the fourth stop portion 211 so that it can only rotate in the first direction from its fourth initial position relative to the electromagnet turntable 20, and the second driving arm 500 is also configured to be able to cooperate with at least the second driving ramp 331; and a second reset member 450, which is arranged between the first driving arm 400 and the second driving arm 500, and the second reset member 450 is, for example, a spring. The driving mechanism is constructed as follows:

[0141] like Figure 14-17 As shown, as the electromagnet rotating disk 20 drives the moving contact driving disk 40 from Fig.14 The first closing position shown is along the second direction ( Fig.14 , 16 and 17 are counterclockwise, Fig.15 (clockwise direction as shown in the figure) to Figure 10-11 In the double split position shown in FIG. 1 , the second driving arm 500 can be subjected to force when contacting the first driving ramp 321 and / or the second driving ramp 331. For example, the second driving arm 500 first contacts the lower end of the first driving ramp 321 and is subjected to force when trying to rotate along the rising direction of the first driving ramp 321 with the electromagnet turntable 20, thereby rotating the electromagnet turntable 20 from the fourth initial position along the first direction ( Fig.15 The second driving arm 500 is rotated in the counterclockwise direction (in the middle), so that the second driving arm 500 can slide over the first driving slope 321 and / or the second driving slope 331. When the moving contact driving disk 40 reaches the double-open position, the second reset member 450 returns the second driving arm 500 to the fourth initial position;

[0142] like Figures 10 to 14 As shown, as the electromagnet rotating disk 20 drives the moving contact driving disk 40 from the double-opening position shown in FIG. 10-11 along the first direction ( Fig.10 , 11 , 13 and 14 are clockwise, Fig.12 (counterclockwise) until Fig.14 In the first closing position shown, the second driving arm 500 begins to contact the lower end of the second driving slope 331. When the second driving arm 500 intends to rotate along the rising direction of the second driving slope 331 with the electromagnet turntable 20, it will abut against the second driving slope 331 to generate a driving force. At this time, the second driving arm 500 cannot rotate relative to the electromagnet turntable 20 due to the stopping effect of the fourth stopper 211. Therefore, the driving force applied to the second driving slope 331 causes the frame 300 to move downward ( Fig.12 );

[0143] As the electromagnet rotary disk 20 drives the moving contact driving disk 40 to rotate from the second closing position to the double opening position along the first direction, the first driving arm 400 can be subjected to force when contacting the second driving slope 331 and / or the first driving slope 321. For example, the first driving arm 400 first contacts the lower end of the second driving slope 331 and is subjected to force when trying to rotate along the rising direction of the second driving slope 331 with the electromagnet rotary disk 20, thereby rotating from the third initial position in the second direction relative to the electromagnet rotary disk 20, so that the first driving arm 400 can slide over the second driving slope 331 and / or the first driving slope 321. When the moving contact driving disk 20 reaches the double opening position, the second reset member 450 returns the first driving arm 400 to the third initial position (not shown).

[0144] As the electromagnet turntable 20 drives the moving contact drive disk 40 to rotate from the double-open position to the second closed position along the second direction, the first drive arm 400 begins to contact the lower end of the first drive ramp 321. When the first drive arm 400 intends to rotate along the rising direction of the first drive ramp 321 with the electromagnet turntable 20, it will abut against the first drive ramp 321 to generate a driving force. At this time, the first drive arm 400 cannot rotate relative to the electromagnet turntable 20 due to the stopping effect of the third stop portion 201. Therefore, the driving force applied to the first drive ramp 321 causes the frame 300 to move downward (not shown).

[0145] That is, in this embodiment, the driving mechanism for driving the frame 300 to move downward has a small number of components and a simple structure. What is more prominent is that the driving mechanism not only structurally utilizes the electromagnet turntable 20 that is usually included in the dual power conversion switch 1, that is, the first driving arm 400 and the second driving arm 500 are installed on the electromagnet turntable 20 in a manner of being constrained by the corresponding stop parts on the electromagnet turntable 20 in one direction, but also utilizes the driving effect of the electromagnet turntable 20 itself in power transmission, that is, the driving force of the first driving arm 400 and the second driving arm 500 on the frame 300 comes from the rotation of the electromagnet turntable 20. On the one hand, this makes full use of the limited space in the dual power conversion switch, so that the setting of the driving mechanism does not occupy more space, thereby realizing a very compact dual power conversion switch. On the other hand, it saves the power source and control components for the driving mechanism, and greatly reduces the cost in both manufacturing and assembly. At the same time, the first driving arm and the driving action of the first driving arm can be perfectly coordinated with the stopping action of the first baffle and the second baffle, so that the entire stopping mechanism has a compact structure, smooth operation, quick response, and is stable and reliable.

[0146] In a more specific embodiment of the stop mechanism 10 according to the present invention, in order to realize the driving mechanism in a simple structure and easy to assemble manner, as shown in FIG. Figure 4-5 , 9 and 12-13, the first driving arm 400 includes a third hole 403 arranged in the middle section and a third corresponding stop portion 401 and a first driving portion 411 respectively arranged on both sides of the third hole, and the third shaft 213 fixed on the electromagnet turntable 20 passes through the third hole 403 to mount the first driving arm 400 on the electromagnet turntable 20 in a rotatable manner relative to the electromagnet turntable 20. The third shaft 213 is, for example, fixed on an axial surface of the electromagnet turntable 20, and the first driving arm 400 is installed so that the third corresponding stop portion 401 cooperates with the third stop portion 201, and the first driving portion 411 cooperates with at least the first driving ramp 321. Optionally, an obtuse angle is formed between the third corresponding stop portion 401 and the first driving portion 411, for example, and the third hole 403 can be arranged in the first material thickening portion 406 of the first driving arm 400, for example. This can ensure that the first driving arm 400 is stopped more firmly and enhance the mechanical strength of the first driving arm 400 so that it can apply driving force to the frame 300 in a more effective manner.

[0147] Accordingly, if Figure 4-5, 9 and 12-13, the second driving arm 500 may also include a fourth hole 503 arranged in the middle section and a fourth corresponding stop portion 501 and a second driving portion 511 respectively arranged on both sides of the fourth hole 503. The fourth shaft 223 fixed on the electromagnet turntable 20 passes through the fourth hole 503 to mount the second driving arm 500 on the electromagnet turntable 20 in a manner that is rotatable relative to the electromagnet turntable 20. The fourth shaft 223 is, for example, fixed on an axial surface of the electromagnet turntable 20, and the second driving arm 500 is installed so that the fourth corresponding stop portion 501 cooperates with the fourth stop portion 211, and the second driving portion 511 cooperates with at least the second driving ramp 331. Similarly, optionally, an obtuse angle is formed between the fourth corresponding stop portion 501 and the second driving portion 511, and the fourth hole 503 can be arranged in the second material thickening portion 506 of the second driving arm 500, for example. This can ensure that the second driving arm 500 is stopped more firmly and the mechanical strength of the second driving arm 500 is enhanced so that it can apply driving force to the frame 300 in a more effective manner.

[0148] Alternatively, if Figure 1-2 As shown, the electromagnet turntable 20 may include two disks spaced apart from each other in the axial direction, and the third shaft 213 and the fourth shaft 223 are fixed between the two disks to facilitate the installation of the third shaft 213 and the fourth shaft 223 .

[0149] In addition, the first driving portion 411 of the first driving arm 400 and the second driving portion 511 of the second driving arm 500 extend parallel to the moving direction of the frame 300 when in the double-split position, which is more conducive to applying driving force to the frame.

[0150] In this case, the stop mechanism 10 is specifically configured to operate as follows:

[0151] like Figure 14-17 As shown, as the electromagnet rotating disk 20 drives the moving contact driving disk 40 from Fig.14 The first closing position shown is along the second direction ( Fig.14 , 16 and 17 are counterclockwise, Fig.15 (clockwise direction as shown in the figure) to Figure 10-11 In the double position shown, the second driving portion 511 of the second driving arm 500 contacts the first driving ramp 321 and / or the second driving ramp 331 and thus moves in the first direction ( Fig.15For example, when the second driving arm 500 contacts the lower end of the first driving ramp 321 and tries to continue to rotate along the rising direction of the first driving ramp 321, the force is applied, and because the fourth stop portion 211 on the electromagnet turntable 20 has no stopping effect on the rotation of the second driving arm 500 in the first direction, the second driving arm 500 rotates along the first direction from the fourth initial position relative to the electromagnet turntable 20, so that the second driving arm 500 can slide over the first driving ramp 321 and / or the second driving ramp 331, and cannot apply downward pressure to the first driving ramp 321 and / or the second driving ramp 331; at the same time, as Fig.16 As shown more clearly, the rotation of the moving contact driving disk 40 causes the stop protrusion 42 thereof to contact and drive the first baffle 100 to move in the first direction ( Fig.16 The stopper protrusion 42 is rotated in the clockwise direction to allow the stopper protrusion 42 to enter the space between the first baffle plate 100 and the second baffle plate 200. Fig.17 The stop convex portion 42 of the moving contact driving disk 40 is stopped from rotating when it abuts against the second baffle plate 200; at this time, the second reset member 450 returns the second driving arm 500 to the fourth initial position, and the first reset member 150 returns the first baffle plate 100 to the first initial position, so that the stop convex portion 42 is firmly stuck between the first baffle plate 100 and the second baffle plate 200, thereby reliably keeping the moving contact in the double-open position;

[0152] like Figures 10 to 14 As shown, as the electromagnet rotating disk 20 drives the moving contact driving disk 40 from Fig.10 and the double split position shown in 11 along the first direction ( Fig.10 and 13 -14 is clockwise, Fig.11 12 is counterclockwise) to the first closing position, the second driving portion 511 of the second driving arm 500 contacts the second driving slope 331, for example, first contacts the lower end of the second driving slope 311 and then intends to rotate along the rising direction of the second driving slope 331. At this time, the second driving arm 500 cannot rotate relative to the electromagnet turntable 20 due to the matching stop effect between its fourth corresponding stop portion 501 and the fourth stop portion 211 of the electromagnet turntable 20. Therefore, as the electromagnet turntable 20 continues to rotate in the first direction, pressure is applied to the second driving slope 331, causing the frame 300 to move downward (such as Fig.12 As shown); this causes the first baffle 100 and the second baffle 200 to move downward to below the stop convex portion 42 of the moving contact driving disk 40, so that the rotation of the stop convex portion 42 is no longer restricted by the first baffle 100 and the second baffle 200, so that the moving contact can be smoothly switched to the first closing position (as shown in FIG. Fig.13 and 14);

[0153] As the electromagnet rotary disk 20 drives the moving contact driving disk 40 to rotate from the second closing position to the double opening position along the first direction, the first driving portion 411 of the first driving arm 400 contacts the second driving slope 331 and / or the first driving slope 321 and is thus subjected to force in the second direction, for example, when it contacts the lower end of the second driving slope 331 and attempts to continue rotating along the rising direction of the second driving slope 331, and because the third stop portion 201 on the electromagnet rotary disk 20 has no stopping effect on the rotation of the first driving arm 400 in the second direction, the first driving arm 400 rotates from the third initial position along the second direction relative to the electromagnet rotary disk 20, so that the first driving arm 400 can slide over the second driving slope 331. and / or the first driving ramp 321, but cannot apply downward pressure to the second driving ramp 331 and / or the first driving ramp 321; at the same time, the rotation of the moving contact driving disk 40 causes its stop convex portion 42 to contact and drive the second baffle plate 200 to rotate along the second direction, thereby allowing the stop convex portion 42 to enter the space between the second baffle plate 200 and the first baffle plate 100, and the stop convex portion 42 of the moving contact driving disk 40 is stopped from rotating when it abuts against the first baffle plate 100; at this time, the second reset member 450 causes the first driving arm 400 to return to the third initial position, and the first reset member 150 causes the second baffle plate 200 to return to the second initial position, so that the stop convex portion 42 is firmly stuck between the second baffle plate 200 and the first baffle plate 100, thereby reliably maintaining the moving contact in the double-open position (not shown);

[0154] As the electromagnet turntable 20 drives the moving contact driving disk 40 to rotate from the double-open position to the second closing position in the second direction, the first driving portion 411 of the first driving arm 400 contacts the first driving slope 321, for example, first contacts the lower end of the first driving slope 321 and then intends to rotate along the rising direction of the first driving slope 321. At this time, the first driving arm 400 cannot rotate relative to the electromagnet turntable 20 due to the matching stop effect between its third corresponding stop portion 401 and the third stop portion 201 of the electromagnet turntable 20. Therefore, as the electromagnet turntable 20 continues to rotate in the second direction, pressure is applied to the first driving slope 321, causing the frame 300 to move downward; this causes the first baffle 100 and the second baffle 200 to move downward to below the stop protrusion 42 of the moving contact driving disk 40, so that the rotation of the stop protrusion 42 is no longer restricted by the first baffle 100 and the second baffle 200, so that the moving contact can be driven to switch smoothly to the second closing position (not shown).

[0155] In order to realize the upward reset of the frame 300 after the downward movement without the aid of external force, as shown in FIG. Figure 1-7As shown, in a more specific embodiment of the stop mechanism 10 according to the present invention, the driving mechanism further includes at least one third reset member arranged in the vertical direction and connected to the frame 300, such as two third reset members 356, 366, and the third reset members 356, 366 are arranged to make the frame 300 move upward to reset after being pressed. Optionally, the third reset members 356, 366 are compression springs. More specifically, the third reset members 356, 366 can be arranged on corresponding support shafts 350, 360 positioned in the vertical direction and connected to the frame 300, and the support shafts are, for example, metal shafts. The stop mechanism 10 is installed in a bracket (such as one or more support plates 61, 62, 63) fixed to the dual power conversion switch 1 through the support shafts 350, 360. That is, the installation of the third reset members 356, 366 does not take up more space, thereby further ensuring the compactness of the stop mechanism 10; at the same time, this can effectively ensure the reset of the frame 300. In this case, as shown in the figure, the support shaft may include an outer tube and an inner tube that can slide relative to each other, the diameter of the outer tube is larger than the diameter of the inner tube, and the compression spring can be sleeved on the inner tube, and the upper end of the compression spring can be fixed to the lower end of the outer tube, and the lower end of the compression spring can be fixed to the mounting bracket 600 of the support shaft, so that when the frame 300 is moved downward, the frame 300 drives the outer tube to move downward, so that the compression spring is compressed downward and stores energy ( Fig.12 When the frame moves downward, the stored energy spring presses the outer tube to move upward, thereby pushing the frame 300 upward to reset ( Figure 12-13 was pressed down, Fig.14 reset).

However, those skilled in the art will appreciate that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention can be combined in various ways without exceeding the scope of protection of the present invention.
