Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliances, in particular to an energy storage operating mechanism of an automatic transfer switch. Background Art

[0002] In the power system, the automatic transfer switch (ATS) is a key device and is widely used to ensure the continuity and reliability of power supply. When the main power supply fails, the ATS can quickly switch the load to the standby power supply, thus avoiding power interruption. The energy storage operating mechanism, as one of the core components of the ATS, is responsible for storing and releasing energy during the switching process to ensure the smoothness and accuracy of the switching action. However, the existing energy storage operating mechanisms of automatic transfer switches generally use link mechanisms as the means of driving and connecting the contact system. Although the functions are realized to a certain extent, there are potential fracture risks during the transmission process. Especially when facing high-frequency or heavy-load switching, it directly affects the service life and reliability of the ATS. Summary of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide an energy storage operating mechanism of an automatic transfer switch with a simple structure, a long service life, and stable and reliable performance.

[0004] To achieve the above purpose, the utility model adopts such an energy storage operating mechanism of an automatic transfer switch. The energy storage operating mechanism includes a first mechanism plate and a second mechanism plate. An energy storage mechanism is arranged between the first mechanism plate and the second mechanism plate. The energy storage mechanism includes an operating runner, a runner link assembly, a spring damping mechanism, and a first central shaft. The operating runner is arranged at one end of the runner link assembly, and long waist slots are respectively arranged on both sides. A first rotating shaft is arranged in the long waist slots. The operating runner is pivotally connected to the runner link assembly through the first rotating shaft. The spring damping mechanism is arranged at the other end of the runner link assembly. The first central shaft is located on one side of the spring damping mechanism. The second mechanism plate is respectively provided with first arc slots on both sides of the first central shaft. A second rotating shaft is arranged in the first arc slots. The spring damping mechanism is pivotally connected to the runner link assembly through the second rotating shaft.

[0005] Compared with the prior art, the beneficial effects of the above structure are as follows: By using the first mechanism plate and the second mechanism plate as the support frame and arranging the energy storage mechanism therebetween, the overall structure is more stable. The design of the runner link assembly effectively disperses the stress during the transmission process, reduces the fracture risk, and thus prolongs the service life of the device. Moreover, the operating runner is pivotally connected to the runner link assembly through the first rotating shaft in the long waist slot, making the transmission process smoother, reducing friction and energy loss, and improving the transmission efficiency. At the same time, the setting of the spring damping mechanism can provide a stable damping effect during energy storage and release, ensuring the smoothness and accuracy of the switching action.

[0006] The utility model is further configured such that the spring damping mechanism includes a spring bracket, a spring, a pivot shaft, a spring piece, and a spring clip. The spring piece is inserted into one end of the spring bracket, the spring clip is inserted into the other end of the spring bracket, the spring is sleeved on the spring bracket, and one end abuts against the spring piece and the other end abuts against the spring clip. The spring bracket axially extends a kidney-shaped hole along one end of the spring piece, and the pivot shaft is inserted into the kidney-shaped hole and contacts the first mechanism plate and the second mechanism plate at both ends. By inserting the spring piece into one end of the spring bracket and the spring clip into the other end, and sleeving the spring on the spring bracket with one end abutting against the spring piece and the other end against the spring clip, the spring can deform when subjected to an external force and store or release energy. The pivot shaft is inserted into the kidney-shaped hole of the spring bracket and contacts the first mechanism plate and the second mechanism plate at both ends, enabling the spring damping mechanism to rotate or swing around the pivot shaft, thereby achieving precise control over the energy storage and release processes.

[0007] The utility model is further configured such that the second mechanism plate is provided with a mechanism rotating disk on the back of the first central axis, and one end of the first central axis contacts the first mechanism plate and the other end passes through the second mechanism plate and is inserted into the mechanism rotating disk. By having one end of the first central axis contact the first mechanism plate and the other end pass through the second mechanism plate and be inserted into the mechanism rotating disk, the overall structure is made more compact, reducing unnecessary space occupation.

[0008] The utility model is further configured such that the first mechanism plate respectively opens second arc grooves at positions corresponding to the second rotating shaft. The second arc grooves correspond to the first arc grooves on the second mechanism plate. One end of the second rotating shaft is inserted into the second arc groove of the first mechanism plate and extends out of the first mechanism plate, and the other end is inserted into the first arc groove of the second mechanism plate and abuts against the mechanism rotating disk. By respectively opening corresponding arc grooves on the first mechanism plate and the second mechanism plate, the second rotating shaft can be accurately inserted therein, thereby achieving precise positioning and fixation between the rotating shaft and the mechanism plate, reducing the risk of failures caused by position deviation or looseness, and enhancing the stability of the overall structure.

[0009] The utility model is further configured such that an upper bypass limiting member and a lower bypass limiting member are wound around the second rotating shaft, and the upper bypass limiting member and the lower bypass limiting member are respectively located between the pivot connection points of the spring damping mechanism and the runner link assembly. The upper bypass limiting member and the lower bypass limiting member can ensure that the second rotating shaft maintains a stable movement trajectory at the pivot connection points.

[0010] The utility model is further configured such that a second central axis is provided on one side of the first central axis. A mechanism rotating shaft is provided on the back surface of the second mechanism plate corresponding to the second central axis. One end of the second central axis contacts the first mechanism plate, and the other end passes through the second mechanism plate and is connected to the mechanism rotating shaft. The mechanism rotating shaft is interlocked with the mechanism rotating disk and is drivingly connected to a contact system. By introducing the second central axis and the mechanism rotating shaft, a multi-stage transmission system is realized, enabling more effective distribution and transmission of power, improving the transmission efficiency, and reducing energy loss.

[0011] The utility model is further configured such that a synchronous motor is provided on the back surface of the first mechanism plate at a position corresponding to the operation rotating wheel. The output end of the synchronous motor is connected to a motor shaft. A composite groove is formed on the first mechanism plate. An indicating member is provided on the back surface of the second mechanism plate at a position corresponding to the operation rotating wheel. A first motor groove matching the motor shaft is formed on the second mechanism plate. A second motor groove is formed on the operation rotating wheel and is aligned with the composite groove on the first mechanism plate. A third motor groove is formed on the indicating member and is aligned with the first motor groove on the second mechanism plate. The motor shaft of the synchronous motor sequentially passes through the composite groove on the first mechanism plate, the second motor groove on the operation rotating wheel, the first motor groove on the second mechanism plate, and the third motor groove of the indicating member, and the end of the motor shaft extends outside the indicating member. By the motor shaft of the synchronous motor sequentially passing through the composite groove on the first mechanism plate, the second motor groove on the operation rotating wheel, the first motor groove on the second mechanism plate, and the third motor groove of the indicating member, the overall structure is made more compact, reducing the gaps between components and unnecessary space occupation, improving the integration degree of the device. An indicating member is provided on the back surface of the second mechanism plate, and the end of the motor shaft extends outside the indicating member, enabling the operator to understand the current state or rotation condition of the operation rotating wheel by observing the position or state of the indicating member, improving the convenience and accuracy of operation.

[0012] The present utility model is further configured such that a lever slot is also provided on the operation rotating wheel, and a limiting lever is arranged in the lever slot. The position of the lever slot corresponds to the part in the composite slot for limiting the lever. A crescent slot matching with the limiting lever is provided on the second mechanism plate.

Limiting slots are respectively provided on both sides of the crescent slot, and a limiting shaft is arranged in the limiting slot. A limiting member is pivotally connected to the limiting shaft, and the limiting member abuts against the end of the limiting lever extending outside the crescent slot. A limiting torsion spring is wound around the limiting shaft, and a torsion spring slot is provided on one side of the limiting slot. One end of the limiting torsion spring contacts the torsion spring slot, and the other end abuts against the limiting member. By having one end of the limiting lever contact the composite slot on the first mechanism plate and the other end inserted into the crescent slot on the second mechanism plate, precise positioning and stable connection between the operation rotating wheel and the second mechanism plate are achieved. The limiting shaft is pivotally connected to the limiting member, and the limiting member abuts against the end of the limiting lever extending outside the crescent slot, which not only limits the movement range of the limiting lever but also prevents its accidental movement in the non-operating state, increasing the stability and safety of the device. The limiting torsion spring is wound around the limiting shaft, with one end contacting the torsion spring slot and the other end abutting against the limiting member. The existence of the limiting torsion spring provides elastic support for the limiting member, enabling the limiting lever to smoothly enter and exit the crescent slot during operation and automatically reset after release, improving the convenience and comfort of operation.

The microswitch assemblies, the microswitch gasket, and the second mechanism plate are connected by screws. By providing the microswitch assemblies on both sides of the mechanism rotating disk, it can be ensured that when the mechanism rotating disk reaches a predetermined position, the microswitch assemblies can act immediately, thereby improving the response speed and accuracy of the device. The microswitch gasket installed at the bottom of the microswitch assemblies can play a role in buffering and shock absorption.
