Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of low-voltage electrical apparatus, and in particular to an operating mechanism and an automatic transfer switching device. BACKGROUND

[0002] The automatic transfer switching device, also known as a dual-power automatic switching device or a dual-power switching device, is used for monitoring a power supply circuit and automatically switching one or several load circuits from one power supply to another power supply.

[0003] Based on the structure of the existing automatic transfer switching device, the automatic transfer switching device includes two sets of energy storage elastic members, and the electrical connection state of the power supply corresponding to the energy storage elastic members and the load is realized by different energy storage elastic members. In order to ensure the use reliability of the automatic transfer switching device, a interlocking mechanism is usually arranged between the two sets of energy storage elastic members to avoid the electrical connection of different power supplies inside the automatic transfer switching device, thereby making the structure of the automatic transfer switching device more complex and being not conducive to the miniaturization development of the automatic transfer switching device. SUMMARY

[0004] The present application provides an operating mechanism and an automatic transfer switching device, which can simplify the structure of the automatic transfer switching device, reduce the manufacturing cost of the automatic transfer switching device, and be conducive to the miniaturization development of the automatic transfer switching device.

[0005] In a first aspect, the present application provides an operating mechanism, which is used for an automatic transfer switching device. The operating mechanism can drive the automatic transfer switching device to switch between an open state and a closed state, and the operating mechanism includes a mounting wall, a rotating assembly, a first limiting block, and a second limiting block.

[0006] The rotating assembly is rotatably mounted to the mounting wall, and a side wall of the rotating assembly is provided with a pushing part. The side of the rotating assembly facing the mounting wall is provided with a first clamping part and a second clamping part at intervals. The first limiting block is rotatably mounted to the mounting wall, and the first limiting block is provided with a third clamping part. The second limiting block is rotatably mounted to the mounting wall, and the second limiting block is provided with a fourth clamping part. The second limiting block is arranged on the side of the rotating assembly away from the first limiting block.

[0007] The automatic transfer switch is in an open state when the rotating assembly is in a position where the first clamping part is clamped with the third clamping part and the second clamping part is clamped with the fourth clamping part. The mounting wall is provided with a clamping protrusion, which is arranged on a rotating path of the first clamping part rotating in the first direction. When the rotating assembly rotates in the first direction, the abutting part abuts against the first limiting block, the third clamping part is separated from the first clamping part, and the rotating assembly continues to rotate in the first direction until the first clamping part is clamped with the clamping protrusion, thereby limiting the rotating assembly from rotating in the first direction, so that the automatic transfer switch is switched from the open state to a closed state, and the load connection end of the automatic transfer switch is electrically connected to the first power supply connection end or the second power supply connection end.

[0008] In the examples of the present application, the mounting wall can provide a mounting carrier for the rotating assembly, the first limiting block and the second limiting block. The first clamping part and the second clamping part are arranged at different positions on the side of the rotating assembly facing the mounting wall, the first limiting block and the second limiting block are arranged on both sides of the rotating assembly, and the third clamping part of the first limiting block can be clamped with the first clamping part, and the fourth clamping part of the second limiting block can be clamped with the second clamping part. That is, the third clamping part cooperates with the first clamping part, and the fourth clamping part cooperates with the second clamping part, which can simultaneously limit the rotating assembly from different positions of the rotating assembly, so that the rotating assembly is maintained in a position that can make the automatic transfer switch in an open state, avoiding the possibility of the automatic transfer switch mistakenly entering a closed state due to the misoperation of the rotating assembly, and ensuring the use reliability of the automatic transfer switch.

[0009] When the automatic transfer switch is in an open state, the abutting part arranged on the rotating assembly can abut against the first limiting block when the rotating assembly rotates in the first direction, so that the first limiting block rotates away from the rotating assembly, and the third clamping part arranged on the first limiting block is separated from the first clamping part. The force applied to the rotating assembly by the first limiting block through the third clamping part disappears, and the rotating assembly can continue to rotate in the first direction until the rotating assembly rotates to a position where the first clamping part is clamped with the clamping protrusion. Since the clamping protrusion is arranged on the rotating path of the first clamping part rotating in the first direction, the clamping of the first clamping part with the clamping protrusion can limit the rotation of the rotating assembly in the first direction, so that the rotating assembly is maintained in a position that can make the automatic transfer switch in a closed state, so that the load connection end of the automatic transfer switch is electrically connected to the first power supply connection end or the second power supply connection end, avoiding the simultaneous electrical connection of the load connection end of the automatic transfer switch to the first power supply connection end and the second power supply connection end due to the misoperation of the rotating assembly, and ensuring the use reliability of the automatic transfer switch.

[0010] Further, compared with the prior art, the interlocking mechanism needs to be separately arranged to avoid the load connection end of the automatic transfer switch electrical appliance being simultaneously electrically connected to the first power supply connection end and the second power supply connection end. In the example of the present application, the first clamping portion provided on the rotating assembly is clamped with the clamping protrusion provided on the mounting wall, and the second clamping portion provided on the rotating assembly is clamped with the clamping protrusion provided on the mounting wall, so that the load connection end of the automatic transfer switch electrical appliance can be avoided from being simultaneously electrically connected to the first power supply connection end and the second power supply connection end, i.e., different power supplies can be avoided from being electrically connected inside the automatic transfer switch electrical appliance, the arrangement of the interlocking mechanism can be reduced, the manufacturing cost of the automatic transfer switch electrical appliance can be reduced, and the miniaturization development of the automatic transfer switch electrical appliance is facilitated.

[0011] In some possible implementation manners, the rotating assembly is further provided with a clamping groove, the clamping groove is arranged between the first clamping portion and the second clamping portion, and when the first clamping portion is clamped with the clamping protrusion, the fourth clamping portion is clamped with the groove wall away from the first clamping portion.

[0012] In the use process of the automatic transfer switch electrical appliance, the clamping protrusion is arranged on the rotating path of the first clamping portion rotating in the first direction, so that the clamping of the first clamping portion with the clamping protrusion can limit the rotation of the rotating assembly in the first direction. On this basis, the clamping of the fourth clamping portion with the groove wall away from the first clamping portion can limit the rotation of the rotating assembly in the second direction, further improve the reliability of the rotating assembly maintaining at the position capable of making the automatic transfer switch electrical appliance in the closed state, avoid the misoperation of the rotating assembly, and further make the load connection end of the automatic transfer switch electrical appliance simultaneously electrically connected to the first power supply connection end and the second power supply connection end, and ensure the use reliability of the automatic transfer switch electrical appliance.

[0013] In some possible implementation manners, the pushing portion includes a first pushing sub-portion, a second pushing sub-portion and a third pushing sub-portion arranged at intervals, the second pushing sub-portion is arranged between the first pushing sub-portion and the third pushing sub-portion, and the first pushing sub-portion and the third pushing sub-portion are arranged away from the mounting wall compared with the second pushing sub-portion.

[0014] The first limiting stopper further includes a first stopper body and a first rib, the first rib is arranged at the middle of the side of the first stopper body away from the mounting wall, the third clamping portion is arranged on the side of the first stopper body facing the rotating assembly, the first pushing sub-portion can push the first rib, and one side of the second pushing sub-portion can push the first stopper body.

[0015] The second limiting stopper further includes a second stopper body and a second rib, the second rib is arranged at the middle of the side of the second stopper body away from the mounting wall, the fourth clamping portion is arranged on the side of the second stopper body facing the rotating assembly, the third pushing sub-portion can push the second rib, and the other side of the second pushing sub-portion can push the second stopper body.

[0016] In the examples of the present application, since the first pushing part and the third pushing part are arranged away from the mounting wall compared with the second pushing part, and the first rib is arranged at the middle of the first block body away from the mounting wall, and the second rib is arranged at the middle of the second block body away from the mounting wall, in the rotation process of the rotating assembly, the second pushing part can contact the first block body to apply a force to the first block body, or in the rotation process of the rotating assembly, the second pushing part can contact the second block body to apply a force to the second block body, so that the rotating assembly realizes switching of different positions, and further realizes switching of the automatic transfer switch between different working states.

[0017] The first pushing part can apply a force to the first rib, so that the first pushing part cooperates with the second pushing part to realize switching of different positions of the rotating assembly, and further realizes switching of the automatic transfer switch between different working states.

[0018] The third pushing part can apply a force to the second rib, so that the third pushing part cooperates with the second pushing part to realize switching of different positions of the rotating assembly, and further realizes switching of the automatic transfer switch between different working states.

[0019] In some possible implementation manners, the first rib includes an abutting rib and a giving space rib, the abutting rib and the giving space rib are arranged at an angle, and the giving space rib extends away from the rotating assembly, and the first pushing part can push the abutting rib, and the giving space rib provides a giving space for rotation of the rotating assembly.

[0020] In the examples of the present application, the abutting rib and the giving space rib are arranged at an angle, and the first pushing part can push the abutting rib, so that the rotating assembly can be switched between the open position and the closed position, and further realizes switching of the automatic transfer switch between the open state and the closed state. The giving space rib extends away from the rotating assembly, so that the giving space rib can provide a giving space for rotation of the rotating assembly, avoiding the situation that the giving space rib contacts the rotating assembly in the rotation process of the rotating assembly, and further causing the rotation process of the rotating assembly to be stuck, ensuring the use reliability of the operating mechanism, and improving the user experience.

[0021] In some possible implementation manners, the rotating assembly includes a cam and a rotating disc. The cam is rotatably mounted to the mounting wall, and the cam is provided with a first clamping part and a second clamping part. The rotating disc cover is arranged on the side of the cam away from the mounting wall, the rotating disc can directly or indirectly drive the cam to rotate, and the side wall of the rotating disc is provided with a pushing part.

[0022] In the examples of the present application, the first clamping portion and the second clamping portion are arranged on the cam, the pushing portion is arranged on the rotating disc, and the rotating disc cover is arranged on the side of the cam away from the mounting wall. Compared with the integrated structure of the rotating disc and the cam, the use of materials of the rotating assembly can be reduced, the manufacturing cost of the rotating assembly can be reduced, and the miniaturization development of the automatic transfer switching apparatus is facilitated.

[0023] In some possible implementation manners, the side of the cam away from the mounting wall is spaced apart from the mounting shaft and the abutting protrusion. The side of the rotating disc facing the cam is provided with the pushing arm. The rotating assembly further comprises a first elastic member. The first elastic member comprises an elastic body, a first torsion arm, and a second torsion arm. The elastic body is mounted on the mounting shaft. The first torsion arm is abutted to one side of the abutting protrusion. The second torsion arm is abutted to the other side of the abutting protrusion. The pushing arm is located between the first torsion arm and the second torsion arm.

[0024] In the examples of the present application, the cam can provide a mounting carrier for the first elastic member. Specifically, the mounting shaft and the abutting protrusion are arranged on the cam. The elastic body of the first elastic member is mounted on the mounting shaft. The first torsion arm of the first elastic member is abutted to one side of the abutting protrusion. The second torsion arm of the first elastic member is abutted to the other side of the abutting protrusion. The pushing arm arranged on the rotating disc is located between the first torsion arm and the second torsion arm. Therefore, during the rotation of the pushing arm, the pushing arm can apply a force to the first torsion arm or the second torsion arm, so that the first elastic member is in an energy storage state. During the further rotation of the rotating assembly, the first elastic member releases energy, so that the rotating assembly can rotate quickly. In turn, the automatic transfer switching apparatus can quickly switch from the open state to the closed state, and the action efficiency of the automatic transfer switching apparatus is improved.

[0025] In addition, compared with the prior art, two independent energy storage elastic members are arranged to realize the electrical connection between the automatic transfer switching apparatus and different power sources, and an interlocking mechanism is arranged to avoid the electrical connection between different power sources in the automatic transfer switching apparatus due to the common action of the two energy storage elastic members. In the examples of the present application, only the first elastic member can store energy for the electrical connection between the first power source and the automatic transfer switching apparatus, or store energy for the electrical connection between the second power source and the automatic transfer switching apparatus. The electrical connection between different power sources in the automatic transfer switching apparatus is avoided, the number of energy storage elastic members can be reduced, the arrangement of the interlocking mechanism is avoided, the number of parts of the automatic transfer switching apparatus can be reduced, the manufacturing cost of the automatic transfer switching apparatus is reduced, and the miniaturization development of the automatic transfer switching apparatus is facilitated.

[0026] In some possible implementation manners, the rotating disc comprises a rotating disc body and a pushing member. The rotating disc body is provided with a fixed slot and a through hole in communication. One end of the pushing member is mounted in the fixed slot, and the other end of the pushing member extends in the direction facing the cam to form the pushing arm.

[0027] In the examples of the present application, the rotating disc body can provide a mounting carrier for the actuating member. Since one end of the actuating member is mounted in the fixed slot, during rotation of the rotating disc, the slot wall of the fixed slot can limit the actuating member, reduce the amplitude of the actuating member relative to the rotating disc body, and ensure the assembly reliability of the actuating member and the rotating disc body. The other end of the actuating member is arranged in the through hole and extends in the direction towards the cam to form an actuating arm, that is, the fixed slot and the through hole of the rotating disc body can limit the actuating member from different positions, reduce the amplitude of the actuating member relative to the rotating disc body, and ensure the connection reliability of the rotating disc body and the actuating member.

[0028] In some possible implementations, the mounting wall is further provided with a first limiting structure and a second limiting structure, the first limiting structure is arranged on the side of the first limiting block away from the rotating assembly, and the second limiting structure is arranged on the side of the second limiting block away from the rotating assembly.

[0029] The operating mechanism further includes a second elastic member and a third elastic member, one end of the second elastic member is abutted to the first limiting structure, the other end of the second elastic member is movably connected to the first limiting block, one end of the third elastic member is abutted to the second limiting structure, and the other end of the third elastic member is movably connected to the second limiting block.

[0030] When the automatic transfer switch is in the open state, the first clamping part and the third clamping part are clamped, at this time, the rotating assembly applies an action force away from the rotating assembly to the first limiting block, so that the first limiting block moves in the direction away from the rotating assembly, and then the second elastic member is in an energy storage state. During rotation of the rotating assembly in the first direction, the first clamping part and the third clamping part are separated, the action force applied by the rotating assembly to the first limiting block is removed, so that the first limiting block can rotate in the direction towards the rotating assembly. At the same time, since one end of the second elastic member is abutted to the first limiting structure, and the first limiting structure is arranged on the side of the first limiting block away from the rotating assembly, the second elastic member releases energy to apply an action force to the first limiting block towards the rotating assembly, which accelerates the speed of the first limiting block rotating towards the rotating assembly, and then improves the efficiency of the third clamping part arranged on the first limiting block and the clamping groove clamped, and then the automatic transfer switch can be quickly switched from the open state to the closed state, and the operation efficiency of the automatic transfer switch is further improved.

[0031] The third elastic member and the second limiting structure have similar effects to the second elastic member and the first limiting structure, which are not described in the examples of the present application.

[0032] In some possible implementation manners, the operating mechanism further includes a mounting shell and a rail clamping limiting piece. The mounting shell includes a mounting wall, and a limiting protrusion and a mounting slot opposite to each other are arranged at the bottom of the mounting shell. The rail clamping limiting piece is slidably mounted to the mounting slot, and the rail clamping limiting piece is clamped to the rail in cooperation with the limiting protrusion.

[0033] In the examples of the present application, the rail clamping limiting piece can be clamped to the rail in cooperation with the limiting protrusion. Since the rail clamping limiting piece is mounted to the mounting shell, and the limiting protrusion is arranged on the shell, and the mounting shell is part of the operating mechanism, the rail clamping limiting piece can be clamped to the rail in cooperation with the limiting protrusion to realize the connection between the rail and the operating mechanism.

[0034] In a second aspect, the present application provides an automatic transfer switching device. The automatic transfer switching device includes a switching body and the operating mechanism provided in the first aspect and possible implementation manners of the first aspect. The operating mechanism can drive the switching body to rotate, so that the automatic transfer switching device is switched between an open state and a closed state.

[0035] The operating mechanism provided in the above second aspect and possible design manners of the second aspect has the beneficial effects of the operating mechanism provided in the above first aspect and possible implementation manners of the first aspect, which will not be described herein again.

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solutions and advantages of the examples of the present application clearer, the technical solutions in the examples of the present application will be described clearly and completely below with reference to the drawings in the examples of the present application. Obviously, the described examples are some examples of the present application, but not all examples of the present application. Based on the examples in the present application, all other examples obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the description herein is for describing particular examples only and is not intended to be limiting of the application; the use herein of terms such as "comprise" and "comprising", and the like, are used in the sense of "including" and "including at least" and are not used in the sense of "consist only of" or "consisting only of".

[0054] Reference herein to "an example" means that a particular feature, structure, or characteristic described in connection with the example can be included in at least one example of the application. The appearances of the phrase "in an example" in various places in the specification are not necessarily all referring to the same example, nor are they necessarily mutually exclusive or alternative examples to one another. It is expressly understood that the examples described herein can be combined with each other in their various permutations.

[0055] The term "and / or", merely used as a description of associated objects, means that there can be three kinds of relations, for example, A and / or B, can mean that A exists, A and B exist, and B exists. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0056] The orientation words appearing in the following description are the directions shown in the drawings, and are not limited to the specific structure of the operating mechanism and the automatic transfer switch of the application.

[0057] In addition, the terms "first", "second", and the like in the specification and claims of the application or the above drawings are used to distinguish different objects, and are not used to describe a specific order, and can explicitly or implicitly include one or more of the features.

[0058] In the description of the application, unless otherwise specified, the meaning of "a plurality of" is two or more (including two), and similarly, "a plurality of groups" means two or more groups (including two groups).

[0059] In the description of the application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, the "connection" or "connection" of the mechanical structure can mean physical connection, for example, the physical connection can be fixed connection, for example, fixed connection through spacer, for example, fixed connection through screws, bolts or other spacers; the physical connection can also be detachable connection, for example, mutual clamping or clamping connection; the physical connection can also be integrally connected, for example, welding, bonding or integrally formed connection. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0060] Based on the above, the examples of the present application provide an operating mechanism and an automatic transfer switching device.

[0061] In order for those skilled in the art to better understand the present application, the operating mechanism and the automatic transfer switching device provided by the examples of the present application will be clearly and completely described below with reference to the drawings.

[0062] Exemplarily, the examples of the present application provide an automatic transfer switching device.

[0063] Figure 1 For the structure diagram of the automatic transfer switching device provided by the examples of the present application, please refer to Figure 1 The automatic transfer switching device 100 includes a switch body 300 and an operating mechanism 200, and the operating mechanism 200 can drive the switch body 300 to rotate, so as to switch the automatic transfer switching device 100 between an open state and a closed state.

[0064] The switch body 300 can be single-phase or multi-phase, and the examples of the present application do not make specific limitations thereto.

[0065] The switch bodies 300 of different phases are similar in structure, and the examples of the present application only take a single-phase switch body 300 as an example to exemplarily describe the structure of the switch body 300.

[0066] The switch body 300 includes a switch housing, and the switch body 300 includes a movable contact assembly and a fixed contact assembly which are matched with each other. The fixed contact assembly is fixedly installed in the switch housing, and the movable contact assembly is rotatably installed in the switch housing.

[0067] The fixed contact assembly includes a load fixed contact, a first power supply fixed contact and a second power supply fixed contact. The load fixed contact is fixedly installed on one side of the switch housing, and the electrical connection between the switch body 300 and the load can be realized through the load fixed contact. The first power supply fixed contact is fixedly installed on the other side of the switch housing, and the electrical connection between the switch body 300 and the first power supply can be realized through the first power supply fixed contact. The second power supply fixed contact is installed on the same side of the switch housing as the first power supply fixed contact, and the second power supply fixed contact and the first power supply fixed contact are arranged in insulation with each other. The electrical connection between the switch body 300 and the second power supply can be realized through the second power supply fixed contact.

[0068] The moving contact assembly comprises a rotating structure and a moving contact body, and the two ends of the moving contact body extend out of the rotating structure to be electrically connected with the stationary contact assembly. The moving contact assembly can be rotated under the driving of the operating mechanism 200, so that the switch body 300 can be switched between the open state and the closed state. When the switch body 300 is in the open state, the automatic transfer switch electric appliance 100 corresponds to the open state, and when the switch body 300 is in the closed state, the automatic transfer switch electric appliance 100 corresponds to the closed state.

[0069] The open state refers to that the ends of the moving contact body are neither electrically connected with the load stationary contact nor electrically connected with any one of the first power supply stationary contact and the second power supply stationary contact.

[0070] The closed state refers to that one end of the moving contact body is electrically connected with the load stationary contact, and the other end of the moving contact body is electrically connected to any one of the first power supply stationary contact and the second power supply stationary contact.

[0071] The automatic transfer switch electric appliance 100 can be electrically connected with different power supplies, so that in the case of failure of one power supply, the load can be electrically connected with another power supply by adjusting the working state of the automatic transfer switch electric appliance 100, thereby ensuring the reliable operation of the load.

[0072] The automatic transfer switch electric appliance 100 can further comprise an indicating structure which is directly or indirectly connected with the operating mechanism 200, so that the operating personnel can know the working state of the automatic transfer switch electric appliance 100 through the indicating structure. In the example of the present application, the indicating structure is similar to the indicating structure of the automatic transfer switch electric appliance in the prior art, which will not be described in detail in the example of the present application.

[0073] For specific description of the operating mechanism 200, please refer to the relevant description below, which will not be described in detail in the example of the present application.

[0074] Since the automatic transfer switch electric appliance 100 provided in the example of the present application comprises the operating mechanism 200 mentioned below, the automatic transfer switch electric appliance 100 provided in the example of the present application has the beneficial effects of the operating mechanism 200 mentioned below.

[0075] Next, the operating mechanism 200 mentioned above will be described in detail.

[0076] Figure 2 A partial explosion structure schematic view of an automatic transfer switch electric appliance provided in the example of the present application, Figure 3 A structure schematic view of a rotating assembly provided in the example of the present application, Figure 4 An explosion structure schematic view of a rotating assembly provided in the example of the present application, Figure 5 A structure schematic view of a cam from a first perspective provided in the example of the present application, Figure 6A structural schematic diagram of a mounting shell provided by the present application.

[0077] Please refer to Figures 1 to 6 Exemplarily, the present application provides an operating mechanism 200 for an automatic transfer switch 100. The operating mechanism 200 can drive the automatic transfer switch 100 to switch between an open state and a closed state, and the operating mechanism 200 comprises a mounting wall 251, a rotating assembly 210, a first limiting block 230, and a second limiting block 240.

[0078] The rotating assembly 210 is rotatably mounted to the mounting wall 251, and a side wall of the rotating assembly 210 is provided with a pushing portion 211. The rotating assembly 210 is spaced apart from the mounting wall 251 and is provided with a first clamping portion 212 and a second clamping portion 213. The first limiting block 230 is rotatably mounted to the mounting wall 251, and the first limiting block 230 is provided with a third clamping portion 231. The second limiting block 240 is rotatably mounted to the mounting wall 251, and the second limiting block 240 is provided with a fourth clamping portion 241. The second limiting block 240 is arranged on a side of the rotating assembly 210 away from the first limiting block 230.

[0079] When the rotating assembly 210 is at a position where the first clamping portion 212 and the third clamping portion 231 are clamped, and the second clamping portion 213 and the fourth clamping portion 241 are clamped, the automatic transfer switch 100 is in the open state. The mounting wall 251 is provided with a clamping protrusion 2511, which is arranged on a rotating path of the first clamping portion 212 in a first direction. When the rotating assembly 210 rotates in the first direction, the pushing portion 211 pushes the first limiting block 230, the third clamping portion 231 is separated from the first clamping portion 212, and the rotating assembly 210 continues to rotate in the first direction until the first clamping portion 212 is clamped with the clamping protrusion 2511, thereby limiting the rotating assembly 210 from rotating in the first direction. This makes the automatic transfer switch 100 switch from the open state to the closed state, and the load connection end 310 of the automatic transfer switch 100 is electrically connected to the first power connection end 320 or the second power connection end 330.

[0080] The operating mechanism 200 can further comprise an operating assembly 220 connected with the rotating assembly 210. The operating assembly 220 can drive the rotating assembly 210 to rotate, thereby making the automatic transfer switch 100 switch between the open state and the closed state.

[0081] The operating assembly 220 can be a motor, an operating handle, or other structures. The operating assembly 220 can also simultaneously comprise a motor and an operating handle. The motor is connected with the rotating assembly 210 through a hole shaft cooperation mode, and the operating handle is connected with the rotating assembly 210 through a gear meshing mode.

[0082] The pushing part 211 is a protruding structure arranged on the side wall of the rotating assembly 210. The pushing part 211 can be arranged in one or multiple.

[0083] The first clamping part 212 and the second clamping part 213 can be a protruding structure arranged on the rotating assembly 210, or a groove structure, a clamping hook structure, etc. The present application does not make specific limitations on this.

[0084] The first limiting block 230 and the second limiting block 240 are arranged on the two opposite sides of the rotating assembly 210. The first limiting block 230 and the second limiting block 240 can be symmetrically or asymmetrically arranged on the two sides of the rotating assembly 210. The present application only takes the first limiting block 230 and the second limiting block 240 symmetrically arranged on the two sides of the rotating assembly 210 as an example for description.

[0085] The third clamping part 231 is arranged on the first limiting block 230, and the fourth clamping part 241 is arranged on the second limiting block 240. The structure of the third clamping part 231 is similar to that of the fourth clamping part 241. The structure of the third clamping part 231 and the fourth clamping part 241 will be described below.

[0086] The third clamping part 231 is clamped with the first clamping part 212. In the case that the first clamping part 212 is a protruding structure, the third clamping part 231 is a groove structure, which can cooperate with the protruding structure to limit the relative position of the first clamping part 212 and the rotating assembly 210. In the case that the first clamping part 212 is a groove structure, the third clamping part 231 is a protruding structure, which can cooperate with the protruding structure to limit the relative position of the first clamping part 212 and the rotating assembly 210. The third clamping part 231 and the first clamping part 212 can be simultaneously arranged as clamping hook structures, and the clamping hooks of the two clamping hook structures are opposite to each other, so that the third clamping part 231 can be clamped with the first clamping part 212.

[0088] In the case where the automatic transfer switch electric appliance 100 is in the open state, the rotating assembly 210 is rotated in the first direction to realize the electrical connection between the load and the first power supply, and the rotating assembly 210 is rotated in the second direction to realize the electrical connection between the load and the second power supply.

[0089] In the case where the automatic transfer switch electric appliance 100 is in the open state, the rotating assembly 210 is rotated in the first direction to realize the electrical connection between the load and the second power supply, and the rotating assembly 210 is rotated in the second direction to realize the electrical connection between the load and the first power supply.

[0090] The first direction can be one of counterclockwise and clockwise, and the second direction is the other one of counterclockwise and clockwise. The examples of the present application are described by taking the first direction as clockwise, the second direction as counterclockwise, and the electrical connection between the load connection end 310 and the first power supply connection end 320 is realized when the rotating assembly 210 is rotated in the first direction as an example.

[0091] Figure 10 An internal structure diagram of the operating mechanism in the closed state provided by the examples of the present application, Figure 11 An internal structure diagram of the operating mechanism in the closed state provided by the examples of the present application, Figure 12 An internal structure diagram of the operating mechanism in the closed state provided by the examples of the present application, Figure 11 A sectional view at B-B.

[0092] As shown in FIG. 1, the automatic transfer switch electric appliance 100 comprises a rotating assembly 210, a moving contact assembly 220, a static contact assembly 230, and an operating mechanism 240. Figures 7 to 12As shown, when the rotating assembly 210 is in the open position, the pushing portion 211 is located between the first limiting block 230 and the second limiting block 240. When the rotating assembly 210 rotates in the clockwise direction, the pushing portion 211 provided on the rotating assembly 210 can push the first limiting block 230, so as to apply a force away from the rotating assembly 210 to the first limiting block 230, and then the third clamping portion 231 provided on the first limiting block 230 can move away from the rotating assembly 210, so that the third clamping portion 231 is separated from the first clamping portion 212 provided on the rotating assembly 210. The rotating assembly 210 can continue to rotate in the clockwise direction until the first clamping portion 212 is clamped to the clamping protrusion 2511, at this time, the rotating assembly 210 is in the first power closing position, the rotating assembly 210 drives the movable contact assembly to rotate to the position electrically connected with the load static contact and the first power static contact, and the automatic transfer switch electric appliance 100 is in the closed state.

[0093] The load static contact and the terminal cooperate to form a load connection end 310, and the first power static contact and the terminal cooperate to form a first power connection end 320.

[0094] When the rotating assembly 210 is in the first power closing position, the rotating assembly 210 rotates in the counterclockwise direction, so that the first clamping portion 212 is separated from the clamping protrusion 2511. The rotating assembly 210 continues to rotate in the counterclockwise direction until the first clamping portion 212 is clamped to the third clamping portion 231, and the second clamping portion 213 is clamped to the fourth clamping portion 241, at this time, the rotating assembly 210 reaches the open position.

[0095] When the rotating assembly 210 is in the open position, the rotating assembly 210 rotates in the counterclockwise direction, so that the pushing portion 211 can push the second limiting block 240, so as to apply a force away from the rotating assembly 210 to the second limiting block 240, and then the fourth clamping portion 241 provided on the second limiting block 240 can move away from the rotating assembly 210, so that the fourth clamping portion 241 is separated from the second clamping portion 213. The rotating assembly 210 can continue to rotate in the counterclockwise direction until the rotating assembly 210 rotates to the position where the second clamping portion 213 is clamped to the clamping protrusion 2511. At this time, the rotating assembly 210 is in the second power closing position, the rotating assembly 210 drives the movable contact assembly to rotate to the position electrically connected with the load static contact and the second power connection end 330, and the automatic transfer switch electric appliance 100 is in the closed state.

[0096] The second power static contact and the terminal cooperate to form a second power connection end 330.

[0097] The process of rotating the rotating assembly 210 from the second power closing position to the open position is similar to the process of rotating the rotating assembly 210 from the first power closing position to the open position, and the present application will not be described here.

[0098] In the example of the present application, the mounting wall 251 can provide a mounting carrier for the rotating assembly 210, the first limiting block 230 and the second limiting block 240. The first clamping portion 212 and the second clamping portion 213 are arranged at different positions of the rotating assembly 210 towards the mounting wall 251, the first limiting block 230 and the second limiting block 240 are arranged on both sides of the rotating assembly 210, and the third clamping portion 231 of the first limiting block 230 can be clamped with the first clamping portion 212, and the fourth clamping portion 241 of the second limiting block 240 can be clamped with the second clamping portion 213, that is, the third clamping portion 231 and the first clamping portion 212 cooperate, and the fourth clamping portion 241 and the second clamping portion 213 cooperate, which can simultaneously limit the rotating assembly 210 from different positions of the rotating assembly 210, so that the rotating assembly 210 is maintained at a position capable of making the automatic transfer switch electrical appliance 100 in the open state, avoiding the possibility of the automatic transfer switch electrical appliance 100 mistakenly entering the closing state due to the misoperation of the rotating assembly 210, and ensuring the use reliability of the automatic transfer switch electrical appliance 100.

[0099] When the automatic transfer switch electrical appliance 100 is in the open state, the pushing portion 211 arranged on the rotating assembly 210 can push the first limiting block 230 when the rotating assembly 210 rotates in the first direction, so that the first limiting block 230 rotates away from the rotating assembly 210, and the third clamping portion 231 arranged on the first limiting block 230 is separated from the first clamping portion 212, the force applied to the rotating assembly 210 by the third clamping portion 231 disappears, and the rotating assembly 210 can continue to rotate in the first direction until the first clamping portion 212 is clamped with the clamping protrusion 2511, because the clamping protrusion 2511 is arranged on the rotating path of the first clamping portion 212 rotating in the first direction, therefore, the clamping of the first clamping portion 212 and the clamping protrusion 2511 can limit the rotation of the rotating assembly 210 in the first direction, so that the rotating assembly 210 is maintained at a position capable of making the automatic transfer switch electrical appliance 100 in the closing state, so that the load connection end 310 of the automatic transfer switch electrical appliance 100 is electrically connected to the first power connection end 320 or the second power connection end 330, avoiding the misoperation of the rotating assembly 210, and further avoiding the simultaneous electrical connection of the load connection end 310 of the automatic transfer switch electrical appliance 100 to the first power connection end 320 and the second power connection end 330, ensuring the use reliability of the automatic transfer switch electrical appliance 100.

[0100] In addition, compared with the prior art, a separate interlocking mechanism is required to avoid the load connection end of the automatic transfer switch electrical appliance being simultaneously electrically connected to the first power supply connection end and the second power supply connection end. In the example of the present application, the first clamping portion 212 provided on the rotating assembly 210 is clamped with the clamping protrusion 2511 provided on the mounting wall 251, and the second clamping portion 213 provided on the rotating assembly 210 is clamped with the clamping protrusion 2511 provided on the mounting wall 251, so as to avoid the load connection end 310 of the automatic transfer switch electrical appliance 100 being simultaneously electrically connected to the first power supply connection end 320 and the second power supply connection end 330, i.e., different power supplies can be avoided from being electrically connected inside the automatic transfer switch electrical appliance 100, the setting of the interlocking mechanism can be reduced, the manufacturing cost of the automatic transfer switch electrical appliance 100 can be reduced, and the miniaturization development of the automatic transfer switch electrical appliance 100 is facilitated.

[0101] Based on the operation mechanism 200 provided in the above example, as shown in Figure 5 and Figures 10 to 12 The rotating assembly 210 is further provided with a clamping groove 214, which is arranged between the first clamping portion 212 and the second clamping portion 213. When the first clamping portion 212 is clamped with the clamping protrusion 2511, the fourth clamping portion 241 is clamped with the groove wall away from the first clamping portion 212 of the clamping groove 214.

[0102] When the second clamping portion 213 is clamped with the clamping protrusion 2511, the third clamping portion 231 is clamped with the groove wall away from the second clamping portion 213 of the clamping groove 214.

[0103] The clamping groove 214 can be arranged close to the rotation center of the rotating assembly 210 compared with the first clamping portion 212 and the second clamping portion 213. The distance between the clamping groove 214 and the rotation center of the rotating assembly 210 can also be equal to the distance between the first clamping portion 212 and the rotation center of the rotating assembly 210, or the distance between the second clamping portion 213 and the rotation center of the rotating assembly 210. The example of the present application does not make specific limitations in this regard.

[0104] When the rotating assembly 210 is in the open position, the rotating assembly 210 rotates in the first direction, and the abutting portion 211 abuts against the first limiting block 230, so that the first limiting block 230 rotates in a direction away from the rotating assembly 210, and the third clamping portion 231 provided on the first limiting block 230 is separated from the first clamping portion 212 provided on the rotating assembly 210. The rotating assembly 210 continues to rotate in the first direction until the first clamping portion 212 is clamped with the clamping protrusion 2511. In addition, since the second clamping portion 213 provided on the rotating assembly 210 is separated from the fourth clamping portion 241 provided on the second limiting block 240, the force applied by the rotating assembly 210 to the second limiting block 240 away from the first limiting block 230 is cancelled, and the second limiting block 240 can rotate in a direction towards the first limiting block 230, thereby enabling the groove wall of the clamping groove 214 to be clamped with the fourth clamping portion 241. Based on this, when the rotating assembly 210 has a tendency to rotate in the second direction, the groove wall of the clamping groove 214 can be clamped with the fourth clamping portion 241, and therefore, the fourth clamping portion 241 is clamped with the groove wall of the clamping groove 214, which can limit the rotation of the rotating assembly 210 in the second direction.

[0105] In the examples of the present application, during the use of the automatic transfer switch 100, since the clamping protrusion 2511 is provided on the rotating path of the first clamping portion 212 rotating in the first direction, the clamping of the first clamping portion 212 with the clamping protrusion 2511 can limit the rotation of the rotating assembly 210 in the first direction. On this basis, the clamping of the fourth clamping portion 241 with the groove wall of the clamping groove 214 away from the first clamping portion 212 can limit the rotation of the rotating assembly 210 in the second direction, further improving the reliability of the rotating assembly 210 maintaining in a position enabling the automatic transfer switch 100 to be in the closed state, avoiding the simultaneous electrical connection of the load connection end 310 of the automatic transfer switch 100 to the first power connection end 320 and the second power connection end 330 due to the misoperation of the rotating assembly 210, and ensuring the use reliability of the automatic transfer switch 100.

[0106] When the second clamping portion 213 is clamped with the clamping protrusion 2511, the third clamping portion 231 is clamped with the groove wall of the clamping groove 214 away from the second clamping portion 213, which has a similar effect to the clamping of the fourth clamping portion 241 with the groove wall of the clamping groove 214 away from the first clamping portion 212 when the first clamping portion 212 is clamped with the clamping protrusion 2511, which will not be described in detail in the examples of the present application.

[0107] Based on the operation mechanism 200 provided in the above examples, the operation mechanism 200 can be used in the automatic transfer switch 100, and the automatic transfer switch 100 can be used in the power supply system 300. Figure 3As shown, the pushing part 211 comprises a first pushing sub-part 2111, a second pushing sub-part 2112 and a third pushing sub-part 2113 which are arranged at intervals, the second pushing sub-part 2112 is arranged between the first pushing sub-part 2111 and the third pushing sub-part 2113, and the first pushing sub-part 2111 and the third pushing sub-part 2113 are arranged away from the mounting wall 251 compared with the second pushing sub-part 2112.

[0108] Figure 13 A structure diagram of a first limiting block is provided for the examples of the present application, please refer to Figure 13 The first limiting block 230 further comprises a first block body 232 and a first rib 233, the first rib 233 is arranged at the middle of the side of the first block body 232 away from the mounting wall 251, the third clamping part 231 is arranged on the side of the first block body 232 facing the rotating assembly 210, the first pushing sub-part 2111 can push the first rib 233, and one side of the second pushing sub-part 2112 can push the first block body 232.

[0109] The second limiting block 240 further comprises a second block body and a second rib, the second rib is arranged at the middle of the side of the second block body away from the mounting wall 251, the fourth clamping part 241 is arranged on the side of the second block body facing the rotating assembly 210, the third pushing sub-part 2113 can push the second rib, and the other side of the second pushing sub-part 2112 can push the second block body.

[0110] The third clamping part 231 is arranged on the first block body 232, and the fourth clamping part 241 is arranged on the second block body.

[0111] Based on the different operation assemblies 220, the positional relationship among the first pushing sub-part 2111, the second pushing sub-part 2112 and the third pushing sub-part 2113 can be different.

[0112] Exemplarily, in the case that the operation assembly 220 comprises an operation handle, the operation handle is connected with the rotating assembly 210 through gear engagement. At this time, the first pushing sub-part 2111 and the second pushing sub-part 2112 are arranged at intervals, and the engagement teeth cooperating with the operation handle are arranged between the first pushing sub-part 2111 and the second pushing sub-part 2112. The second pushing sub-part 2112 is arranged on the side of the engagement teeth close to the mounting wall 251.

[0113] In the case that the operating assembly 220 only includes the motor, the pushing part is an integrated structure, the cross section of the pushing part 211 is in a "convex" shape, the end of the convex pushing part with a smaller cross section corresponds to the second pushing part, and is arranged towards the mounting wall 251, the side of the end of the convex pushing part with a larger cross section is the first pushing part, and the other side is the third pushing part. The specific structure of the pushing part 211 is not limited in the examples of the present application. The following will be described only by taking the example that the first pushing part 2111, the second pushing part 2112 and the third pushing part 2113 are arranged at intervals.

[0114] As shown in Figure 7 , when the rotating assembly 210 is in the open position, the pushing part 211 is located between the first limiting block 230 and the second limiting block 240, specifically, the second pushing part 2112 is located between the first block body 232 and the second block body, the first pushing part 2111 is located on the side of the first rib 233 towards the second limiting block 240, and the third pushing part 2113 is located on the side of the second rib towards the first limiting block 230.

[0115] In the rotating process of the rotating assembly 210 rotating in the first direction, the second pushing part 2112 can first push the first block body 232, so that the first limiting block 230 rotates in the direction away from the rotating assembly 210, so that the third clamping part 231 is separated from the first clamping part 212, and then the rotating assembly 210 can continue to rotate, so that the automatic transfer switch electric appliance 100 is switched from the open state to the closed state, at this time, the load connection end 310 of the automatic transfer switch electric appliance 100 is electrically connected with the first power supply connection end 320.

[0116] Please refer to Figure 10 and Figure 12In the case that the load connection end 310 of the automatic transfer switch 100 is electrically connected with the first power supply connection end 320, during the rotation of the rotating assembly 210 in the second direction, the third pushing part 2113 can push the second rib, and since the second rib is arranged on the second limiting block 240, under the action of the third pushing part 2113, the second limiting block 240 can move in a direction away from the rotating assembly 210, and further, the fourth clamping part 241 is separated from the slot wall of the clamping slot 214, the action force of the fourth clamping part 241 on the slot wall of the clamping slot 214 for limiting the rotation of the rotating assembly 210 in the second direction is removed, and thus the rotating assembly 210 can continue to rotate in the second direction. During the rotation of the rotating assembly 210 in the second direction, the rotating assembly 210 pushes the first limiting block 230, so that the first limiting block 230 rotates in a direction away from the rotating assembly 210, and the possibility of the first limiting block 230 limiting the rotation of the rotating assembly 210 in the second direction is reduced, so that the rotating assembly 210 can rotate to a position where the first clamping part 212 is clamped with the third clamping part 231, and the second clamping part 213 is clamped with the fourth clamping part 241, so that the automatic transfer switch 100 is switched from the closed state to the open state.

[0117] When the rotating assembly 210 is in the open position, during the rotation of the rotating assembly 210 in the second direction, the second pushing part 2112 can first push the second block body, so that the second limiting block 240 rotates in a direction away from the rotating assembly 210, so that the fourth clamping part 241 is separated from the second clamping part 213, and further, the rotating assembly 210 can continue to rotate, so that the automatic transfer switch 100 is switched from the open state to the closed state, and at this time, the load connection end 310 of the automatic transfer switch 100 is electrically connected with the second power supply connection end 330.

[0118] In the case that the load connection end 310 of the automatic transfer switch 100 is electrically connected with the second power connection end 330, in the process of rotating the rotating assembly 210 in the first direction, the first pushing part 2111 can push the first rib 233. Since the first rib 233 is arranged on the first limiting block 230, under the action of the first pushing part 2111, the first limiting block 230 can move away from the rotating assembly 210, thereby making the third clamping part 231 separate from the clamping groove 214, and the action force of the rotating assembly 210 rotating in the first direction through the slot wall of the clamping groove 214 is removed, so that the rotating assembly 210 can continue to rotate in the first direction. In the process of rotating the rotating assembly 210 in the first direction, the rotating assembly 210 pushes the second limiting block 240, so that the second limiting block 240 rotates away from the rotating assembly 210, reducing the possibility of the second limiting block 240 limiting the rotating assembly 210 rotating in the first direction, so that the rotating assembly 210 can rotate to the position where the second clamping part 213 and the fourth clamping part 241 are clamped, and the first clamping part 212 and the third clamping part 231 are clamped, so that the automatic transfer switch 100 is switched from the closed state to the open state.

[0119] In the examples of the present application, since the first pushing part 2111 and the third pushing part 2113 are arranged away from the mounting wall 251 compared with the second pushing part 2112, and the first rib 233 is arranged on the middle of the first block body 232 away from the mounting wall 251, and the second rib is arranged on the middle of the second block body away from the mounting wall 251, in the process of rotating the rotating assembly 210, the second pushing part 2112 can contact the first block body 232 to apply an action force to the first block body 232, or in the process of rotating the rotating assembly 210, the second pushing part 2112 can contact the second block body to apply an action force to the second block body, so that the rotating assembly 210 realizes switching of different positions, thereby realizing switching of the automatic transfer switch 100 between different working states.

[0120] The first pushing part 2111 can apply an action force to the first rib 233, so that the first pushing part 2111 cooperates with the second pushing part 2112 to realize switching of different positions of the rotating assembly 210, thereby realizing switching of the automatic transfer switch 100 between different working states.

[0121] The third pushing part 2113 can apply an action force to the second rib, so that the third pushing part 2113 cooperates with the second pushing part 2112 to realize switching of different positions of the rotating assembly 210, thereby realizing switching of the automatic transfer switch 100 between different working states.

[0122] The first rib 233 and the second rib have similar structures. Next, the structure of the first rib 233 and the second rib will be described by taking the first rib 233 as an example.

[0123] Please refer to Figure 13 The first rib 233 includes an abutting rib 2331 and a space-providing rib 2332. The abutting rib 2331 and the space-providing rib 2332 are arranged at an angle, and the space-providing rib 2332 extends away from the rotating assembly 210. The first pushing part 2111 can push the abutting rib 2331, and the space-providing rib 2332 provides a space for the rotation of the rotating assembly 210.

[0124] The abutting rib 2331 and the space-providing rib 2332 can be connected or spaced.

[0125] The angle formed by the abutting rib 2331 and the space-providing rib 2332 can be a right angle, an acute angle, or an obtuse angle.

[0126] The space-providing rib 2332 extends away from the rotating assembly 210, which can form a straight rib or an arc-shaped rib, as long as it can provide a space for the rotation of the rotating assembly 210. The present application does not make specific limitations on this. The present application only illustrates the space-providing rib 2332 as an arc-shaped rib.

[0127] In the present application, the abutting rib 2331 and the space-providing rib 2332 are arranged at an angle, and the first pushing part 2111 can push the abutting rib 2331, so that the rotating assembly 210 can be switched between the open position and the closed position, thereby realizing the switching of the automatic transfer switch 100 between the open state and the closed state. The space-providing rib 2332 extends away from the rotating assembly 210, so that the space-providing rib 2332 can provide a space for the rotation of the rotating assembly 210, avoiding the situation that the rotating assembly 210 is stuck during the rotation process due to the contact between the space-providing rib 2332 and the rotating assembly 210, thereby ensuring the use reliability of the operating mechanism 200 and improving the user experience.

[0128] Based on the operating mechanism 200 provided in the above example, the mounting wall 251 is further provided with a first sliding groove and a second sliding groove, and the first sliding groove and the second sliding groove are arranged on different sides of the rotating assembly 210.

[0129] One end of the first limiting stopper 230 is rotatably connected to the mounting wall 251 through a first rotating shaft, and the other end extends into the first sliding groove. During the rotation of the first limiting stopper 230 relative to the mounting wall 251, the other end of the first limiting stopper 230 slides in the first sliding groove.

[0130] One end of the second limiting block 240 is rotatably connected to the mounting wall 251 through a second rotating shaft, and the other end extends into the first sliding groove, and during the rotation of the second limiting block 240 relative to the mounting wall 251, the other end of the second limiting block 240 slides in the first sliding groove.

[0131] In the example of the present application, one end of the first limiting block 230 is rotatably connected to the first rotating shaft, and the other end extends into the first sliding groove, so that the first rotating shaft and the first sliding groove can limit the first limiting block 230 from different positions, ensuring the connection reliability of the first limiting block 230 and the mounting wall 251. One end of the second limiting block 240 is rotatably connected to the second rotating shaft, and the other end extends into the second sliding groove, so that the second rotating shaft and the second sliding groove can limit the second limiting block 240 from different positions, ensuring the connection reliability of the second limiting block 240 and the mounting wall 251.

[0132] Based on the operation mechanism 200 provided in the above example, please refer to Figure 4 and Figure 5 The rotating assembly 210 includes a cam 215 and a rotating disc 216. The cam 215 is rotatably mounted to the mounting wall 251, and the cam 215 is provided with a first clamping portion 212 and a second clamping portion 213. The rotating disc 216 is covered on the side of the cam 215 away from the mounting wall 251, and the rotating disc 216 can directly or indirectly drive the cam 215 to rotate, and the side wall of the rotating disc 216 is provided with a pushing portion 211.

[0133] The rotating disc 216 and the cam 215 can be connected by hole shaft cooperation to enable the rotating disc 216 to drive the cam 215 to rotate relative to the mounting wall 251. The rotating disc 216 and the cam 215 can be directly connected, and a spring or other connecting member can also be provided between the rotating disc 216 and the cam 215.

[0134] The first clamping portion 212 and the second clamping portion 213 mentioned in the foregoing are provided on the cam 215, specifically on the side of the cam 215 facing the mounting wall 251. In the case that the rotating assembly 210 is provided with a clamping groove 214, the clamping groove 214 is provided on the cam 215. The pushing portion 211 is provided on the side wall of the rotating disc 216.

[0135] The operation assembly 220 mentioned in the foregoing drives the cam 215 to rotate through the rotating disc 216. In the case that the operation assembly 220 includes a motor, the motor is connected with the rotating disc 216 by hole shaft cooperation to drive the rotating disc 216 to rotate. In the case that the operation assembly 220 includes an operation handle, the operation handle is engaged with the rotating disc 216 to drive the rotating disc 216 to rotate.

[0136] In the example of the present application, the first clamping portion 212 and the second clamping portion 213 are arranged on the cam 215, and the pushing portion 211 is arranged on the rotating disc 216. The rotating disc 216 is arranged on the side of the cam 215 away from the mounting wall 251. Compared with the integrated structure of the rotating disc 216 and the cam 215, the use of materials of the rotating assembly 210 can be reduced, the manufacturing cost of the rotating assembly 210 can be reduced, and the miniaturization development of the automatic transfer switch apparatus 100 is facilitated.

[0137] Based on the operation mechanism 200 provided in the above example, Figure 14 For the second perspective view of the structure of the cam provided in the example of the present application, please refer to Figure 4 With Figure 14 The side of the cam 215 away from the mounting wall 251 is spaced apart from the mounting shaft 2151 and the abutting protrusion 2152. The side of the rotating disc 216 facing the cam 215 is provided with a poking arm. The rotating assembly 210 further includes a first elastic member 217. The first elastic member 217 includes an elastic body, a first torsion arm, and a second torsion arm. The elastic body is mounted on the mounting shaft 2151. The first torsion arm abuts one side of the abutting protrusion 2152. The second torsion arm abuts the other side of the abutting protrusion 2152. The poking arm is located between the first torsion arm and the second torsion arm.

[0138] The first elastic member 217 can be a torsion spring, a leaf spring, or other elastic member. In the example of the present application, only the case where the first elastic member 217 is a torsion spring is described.

[0139] The abutting protrusion 2152 can be arranged close to the edge of the cam 215. In the case where the rotating disc 216 cooperates with the cam 215, the first torsion arm and the second torsion arm can abut the two sides of the abutting protrusion 2152 arranged opposite to each other. The mounting shaft 2151 is arranged close to the middle of the cam 215. The center line of the mounting shaft 2151 can be collinear with the center line of the cam 215. The rotating disc 216 can cooperate with the cam 215 through the mounting shaft 2151. The elastic body is mounted on the mounting shaft 2151. Specifically, the elastic body can be sleeved on the mounting shaft 2151.

[0140] The poking arm is a protrusion protruding from the rotating disc 216 toward the side of the cam 215. In the case where the rotating disc 216 cooperates with the cam 215, the poking arm is located between the first torsion arm and the second torsion arm. The poking arm can be integrally formed with the rotating disc 216, or the poking arm can be a separate component from the rotating disc 216.

[0141] The first torsion arm can be located on the rotation path of the poking arm rotating in the first direction. At this time, the second torsion arm is located on the rotation path of the poking arm rotating in the second direction. Alternatively, the first torsion arm can be located on the rotation path of the poking arm rotating in the second direction. At this time, the second torsion arm is located on the rotation path of the poking arm rotating in the first direction.

[0142] During the rotation of the rotating assembly 210 in the first direction, since the rotating disc 216 is directly connected with the operating assembly 220, the rotating disc 216 rotates first compared with the mounting wall 251. The first torsion arm is located on the rotation path of the toggle arm rotating in the first direction, so that the toggle arm can exert a force in the first direction on the first torsion arm during the rotation of the toggle arm in the first direction, at this time, the second torsion arm abuts to the other side of the abutting protrusion 2152, the first torsion arm deforms under the action of the toggle arm, so that the first elastic member 217 stores energy. During the process that the abutting part 211 exerts a force on the first limit stop 230, so that the first clamping part 212 provided on the rotating assembly 210 is separated from the third clamping part 231 provided on the first limit stop 230, the first elastic member 217 releases energy, under the action of the first elastic member 217, the cam 215 quickly rotates to the position where the first clamping part 212 is clamped with the clamping protrusion 2511, so that the rotating assembly 210 can quickly switch from the open position to the first power closing position.

[0143] During the rotation of the rotating assembly 210 in the second direction, the second torsion arm is located on the rotation path of the toggle arm rotating in the second direction, so that the toggle arm can exert a force in the second direction on the second torsion arm during the rotation of the toggle arm in the second direction, at this time, the first torsion arm abuts to the other side of the abutting protrusion 2152, the second torsion arm deforms under the action of the toggle arm, so that the first elastic member 217 stores energy. During the process that the abutting part 211 exerts a force on the second limit stop 240, so that the second clamping part 213 provided on the rotating assembly 210 is separated from the fourth clamping part 241 provided on the second limit stop 240, at this time, the first elastic member 217 releases energy, under the action of the first elastic member 217, the cam 215 quickly rotates to the position where the second clamping part 213 is clamped with the clamping protrusion 2511, so that the rotating assembly 210 can quickly switch from the open position to the second power closing position.

[0144] During the process that the rotating assembly 210 switches from the first power closing position to the open position, or switches from the second power closing position to the open position, the first elastic member 217 can speed up the action efficiency of the rotating assembly 210.

[0145] In this example, the cam 215 can provide a mounting carrier for the first elastic element 217. Specifically, the cam 215 is provided with a mounting shaft 2151 and an abutment protrusion 2152. The elastic body of the first elastic element 217 is mounted to the mounting shaft 2151. The first torsion arm of the first elastic element 217 abuts against one side of the abutment protrusion 2152, and the second torsion arm abuts against the other side of the abutment protrusion 2152. The actuating arm of the turntable 216 is located between the first torsion arm and the second torsion arm. Therefore, during the rotation of the actuating arm, the actuating arm can apply a force to the first or second torsion arm, so that the first elastic element 217 is in an energy storage state. During the further rotation of the rotating assembly 210, the first elastic element 217 releases energy, so that the rotating assembly 210 can rotate quickly, thereby enabling the automatic transfer switch 100 to quickly switch from the open state to the closed state, improving the operating efficiency of the automatic transfer switch 100.

[0146] Furthermore, compared to existing technologies that use two independent energy storage elastic elements to achieve electrical connection between the automatic transfer switch and different power sources, and which employ interlocking mechanisms to prevent different power sources from being electrically connected within the automatic transfer switch due to the combined action of the two energy storage elastic elements, the example in this application uses only the first elastic element 217 to store energy for the electrical connection between the first power source and the automatic transfer switch 100, as well as for the electrical connection between the second power source and the automatic transfer switch 100. This avoids different power sources being electrically connected within the automatic transfer switch 100, reducing the number of energy storage elastic elements and eliminating the need for interlocking mechanisms. This reduces the number of components in the automatic transfer switch 100, lowers its manufacturing cost, and facilitates its miniaturization.

[0147] Based on the operating mechanism 200 provided in the above example, please refer to... Figure 4 The turntable 216 includes a turntable body 2161 and a toggle member 2162. The turntable body 2161 is provided with a connecting fixed groove and a through hole. One end of the toggle member 2162 is installed in the fixed groove, and the other end of the toggle member 2162 passes through the through hole and extends in the direction toward the cam 215 to form a toggle arm.

[0148] The pusher 211 mentioned above is located on the side wall of the turntable body 2161.

[0149] The centerline of the fixing groove and the centerline of the through hole can be on the same straight line, or they can be set at an angle. Figure 4 Only the actuating member 2162, whose center line of the fixing groove is set at an angle to the center line of the perforation, is shown in the illustration.

[0150] When the center line of the fixed groove and the center line of the perforation are set at an angle, taking the case where the center line of the fixed groove and the center line of the perforation are basically perpendicular, the actuating member 2162 is roughly right-angled, that is, the two ends of the actuating member 2162 are basically right-angled.

[0151] The centerline of the fixing groove is substantially perpendicular to the centerline of the perforation, meaning that the angle formed by the centerline of the fixing groove and the centerline of the perforation is less than or equal to 95° and greater than or equal to 85°. The difference between the angle formed by the two ends of the actuating element 2162 and the angle formed by the centerline of the fixing groove and the centerline of the perforation is less than or equal to 3°.

[0152] The motor can be connected to the turntable body 2161 by passing through the toggle member 2162, or the motor can be spaced apart from the toggle member 2162.

[0153] One end of the actuating member 2162 is installed in the fixed groove, and the other end of the actuating member 2162 passes through the through hole and extends in the direction toward the cam 215 to form an actuating arm, which extends between the first torsion arm and the second torsion arm.

[0154] In this example, the turntable body 2161 provides a mounting carrier for the actuating element 2162. Since one end of the actuating element 2162 is installed in the fixed groove, the groove wall of the fixed groove can limit the actuating element 2162 during the rotation of the turntable 216, reducing the amplitude of the actuating element 2162's wobbling relative to the turntable body 2161 and ensuring the assembly reliability of the actuating element 2162 and the turntable body 2161. The other end of the actuating element 2162 passes through the through hole and extends towards the cam 215 to form an actuating arm. That is, the fixed groove and through hole in the turntable body 2161 can limit the actuating element 2162 from different positions, reducing the amplitude of the actuating element 2162's wobbling relative to the turntable body 2161 and ensuring the connection reliability between the turntable body 2161 and the actuating element 2162.

[0155] Based on the operating mechanism 200 provided in the above example, please refer to... Figure 5 , Figure 7 as well as Figure 10 The mounting wall 251 is also provided with a first limiting structure 2512 and a second limiting structure 2513. The first limiting structure 2512 is located on the side of the first limiting block 230 away from the rotating component 210, and the second limiting structure 2513 is located on the side of the second limiting block 240 away from the rotating component 210.

[0156] The operating mechanism 200 also includes a second elastic member 260 and a third elastic member 270. One end of the second elastic member 260 abuts against the first limiting structure 2512, and the other end of the second elastic member 260 is movably connected to the first limiting block 230. One end of the third elastic member 270 abuts against the second limiting structure 2513, and the other end of the third elastic member 270 is movably connected to the second limiting block 240.

[0157] The first limiting structure 2512 can be an arc-shaped protrusion or a straight protrusion. There can be only one first limiting structure 2512, or there can be multiple first limiting structures 2512 spaced apart.

[0158] The second limiting structure 2513 can be an arc-shaped protrusion or a straight protrusion. There can be only one second limiting structure 2513, or there can be multiple second limiting structures 2513 spaced apart. The second limiting structure and the first limiting structure 2512 are symmetrically distributed on both sides of the snap-fit ​​protrusion 2511.

[0159] The second elastic element 260 and the third elastic element 270 can be elastic elements such as torsion springs, V-springs, and elastic sheets.

[0160] The first limiting block 230 and the second limiting block 240 have similar structures. The following description will use the first limiting block 230 as an example to illustrate the structure of the first limiting block 230 and the second limiting block 240.

[0161] The first limiting block 230 is provided with a mounting hole. When the first limiting block 230 includes a first block body 232 and a first rib 233, the mounting hole can be provided on the first block body 232 and on the side of the first rib 233 away from the rotating component 210, so as to reduce the possibility that the second elastic member 260 will affect the rotation of the rotating component 210.

[0162] The mounting hole can be a strip-shaped hole, and the shape of the mounting hole can also be adapted to the shape of the first rib 233. This application does not impose specific restrictions on this, as long as the end of the second elastic member 260 can slide in the mounting hole.

[0163] When the automatic transfer switch 100 is in the open state, the first latching part 212 latches with the third latching part 231. At this time, the rotating component 210 applies a force away from the rotating component 210 to the first limit block 230, causing the first limit block 230 to move in a direction away from the rotating component 210, thereby causing the second elastic member 260 to be in an energy storage state. During the rotation of the rotating assembly 210 in the first direction, the first engaging part 212 and the third engaging part 231 separate, and the force applied by the rotating assembly 210 to the first limiting block 230 is removed, allowing the first limiting block 230 to rotate in the direction toward the rotating assembly 210. At the same time, since one end of the second elastic member 260 abuts against the first limiting structure 2512, and the first limiting structure 2512 is located on the side of the first limiting block 230 away from the rotating assembly 210, the energy released by the second elastic member 260 can apply a force toward the rotating assembly 210 to the first limiting block 230, accelerating the rotation speed of the first limiting block 230 toward the rotating assembly 210, thereby improving the engagement efficiency of the third engaging part 231 and the engaging groove 214 on the first limiting block 230, and thus enabling the automatic transfer switch 100 to quickly switch from the open state to the closed state, further improving the operating efficiency of the automatic transfer switch 100.

[0164] The third elastic element 270 and the second limiting structure 2513 have similar functions to the second elastic element 260 and the first limiting structure 2512, and will not be described in detail here.

[0165] The third elastic element 270, the second limiting structure 2513, and the second limiting block 240 work together to achieve similar effects as the second elastic element 260, the first limiting structure 2512, and the first limiting block 230 work together. This application example will not be described in detail here.

[0166] Based on the operating mechanism 200 provided in the above example, please refer to... Figure 1 and Figure 2 The operating mechanism 200 also includes a mounting housing 250 and a rail limiting member 400. The mounting housing 250 includes the mounting wall 251 mentioned above, and the bottom of the mounting housing 250 is provided with a limiting boss and a mounting groove that are positioned opposite each other. The rail limiting member 400 is slidably mounted to the mounting groove, and the rail limiting member 400 engages with the rail by cooperating with the limiting boss.

[0167] The bottom of one or more housings, such as the mounting housing 250 and the switch housing, may be provided with a limiting boss and a mounting groove that are positioned opposite each other. This application example does not impose specific limitations on this.

[0168] The mounting housing 250 can be made of insulating materials, such as polyvinyl chloride, polycarbonate (also known as PC plastic), etc. A mounting housing 250 made of insulating material reduces the possibility of current escaping from the housing to the outside, ensuring the safety of the operating mechanism 200, and thus ensuring the safety of the automatic transfer switch 100.

[0169] When the rail limiting member 400 is not subjected to external force, the distance between the side of the rail limiting member 400 facing the limiting boss and the limiting boss is less than the size of the rail limiting member 400 in the direction of the mounting groove pointing to the limiting boss.

[0170] The rail-mounting member is slidably installed into the mounting groove. During the installation of the operating mechanism 200 onto the rail, the rail pushes against the rail-mounting member 400, causing the rail-mounting member 400 to move within the mounting groove away from the limiting boss, thereby positioning the rail between the limiting boss and the mounting groove. After the rail is in contact with the bottom wall of the housing, the force applied to the rail-mounting member 400 is removed, and the rail-mounting member 400 moves towards the limiting boss. The side of the rail-mounting member 400 facing the limiting boss can extend out of the mounting groove, allowing the rail-mounting member 400 to engage with the limiting boss to connect the housing and the rail.

[0171] In this application example, the rail limiting member 400 can engage with the rail by cooperating with the limiting boss. Since the rail limiting member 400 is installed on the mounting housing 250 and the limiting boss is located on the mounting housing 250, and the mounting housing 250 is part of the operating mechanism 200, the rail limiting member 400 engaging with the rail by cooperating with the limiting boss can realize the connection between the rail and the operating mechanism 200.

[0172] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
