Description

    Background of the invention 1. Field of the Invention
  • The present invention relates to the field of low-pressure electric appliances, and more particularly, to an operating system of automatic changeover switch.
    • 2. The related art
  • The existing operating system of an integrative automatic changeover switch mostly utilizes an electromagnet, a linear motor to or manually rotates and connects to the principal axis on the common power supply side or the spare power supply side, so as to drive the contact system to move to a closed position. Since the force generated by electromagnet is limited by volume, and direct manual operation can hardly result in large operating forces, the capacity of the changeover switch is limited. If a high-capacity integrative automatic changeover switch utilizes an existing electromagnet, a linear motor, or an operating system operated manually, a very large volume is required, and the reliability is relatively low.
  • The patent application with the application number of 200910047109.X discloses a three-gear switch mechanism of an electric appliance. The three-gear switch mechanism comprises: a first gear connected to a first contact, the rotation of the first gear drives the first contact to close to or open from a first power supply; a second gear connected to a second contact, the rotation of the second gear drives the second contact to close to or open from a second power supply, the first gear not contacting the second gear; and an active gear engages and drives the second gear to rotate, the rotation direction of the active gear being opposite to that of the first gear and the second gear. The active gear rotates along a second direction, drives the first gear to rotate along a first direction so that the first contact is separated from the first power supply from a closed position to an open position, drives the second gear to rotate along the first direction so that the second contact approaches the second power supply from an open position to a closed position. This switch mechanism is simple and reliable, utilizes different engagement conditions of gear set to achieve the switch of positions, leaves out the use of electromagnet, improves reliability while simplify the structure. The solution of this parent application is an incomplete three-gear solution, which has a high requirement on the processing technology and low reliability, and is used in the change of switch of non pre storage operational structure.
  • The patent application with the application number of 200910047108.5 discloses a double-storage operational mechanism with a single operational axis that is used in an automatic changeover switching appliance. The double-storage operational mechanism comprises: an operating handle and an operating motor that are positioned at a first side of a mounting plate of the operational mechanism of the automatic changeover switching appliance, the operating handle and the operating motor being set in a first operating cam principle axis and drives the rotation of the first operating cam principle axis; a drive gear that are positioned at a second side of the mounting plate of the operational mechanism, the drive gear connects the first operating cam principle axis and a second operating cam principle axis of the operational mechanism, the rotation of the first operating cam principle axis drives the rotation of the second operating cam principle axis via the drive gear; a storage mechanism that connects to the first operating cam principle axis via a first cam and connects to the second operating cam principle axis via a second cam, the energy generated from the rotations of the first operating cam principle axis and the second operating cam principle axis are respectively stored by driving the storage mechanism respectively with the first cam and the second cam. The solution of this patent application is a solution that utilizes two gears. This solution cannot assure the precise location of the double-storage operational mechanism, cannot assure that the storage operation of a second storage mechanism starts after the storage operation of a first storage mechanism ends, has a low reliability, and has a possibility of misoperation and gear stuck.

          • a common side drive gear 108a connected to the common side drive axis 118 and has a common side clutch 110a mounted thereon;
          • a spare side drive gear 108b connected to the spare side drive axis 119 and has a spare side clutch 110b mounted thereon;
          • a common side transmission gear 109a and a spare side transmission gear 109b that are both connected to a common axis 111, the common side transmission gear 109a engages the common side drive gear 108a, while the spare side transmission gear 109b engages the spare side drive gear 108b;
          • a changeover gear 107 that engages the common side transmission gear 108a;
          • an operating handle 112 and a motor 113 that are connected to and drive the common axis 111, and are shown in Figure 1;
          • a side plate 114 that has a ratchet gear 115, a ratchet paw 116, and a spring 117 mounted thereon, where the ratchet gear 115 engages the ratchet paw 116, where the spring 117 connects to an end of the ratchet paw 116, where the side plate 114, the ratchet gear 115, the ratchet paw 116, and the spring 117 are shown in Figure 3.
  • The rotation of the operating handle 112 and the motor 113 drives the rotation of the common axis 111, while the rotation of the common axis 111 drives the rotation of the gear set. The rotation of the operating handle 112 and the motor 113 drives the rotation of the common axis 111 within the range of 0°-150° so as to store energy for the common side operational mechanism, and within the range of 150°-300° so as to store energy for the spare side operational mechanism.
  • The operating handle 112 and the motor 113 are in the middle position so that the operating system is disconnected from the common side power supply and the spare side power supply. The rotation of the operating handle 112 and the motor 113 drives the rotation of the common axis 111. The common axis 111 transfers the torque to the common side drive axis 118 through the common side transmission gear 109a and by driving the changeover gear 108 and the common side drive gear 108a. The rotation of the common side cam 101 is driven by the common side drive axis 118. The common side cam 101 drives the rotation of the common side storage lever 104a, and compress the common side storage spring to store energy. When the common axis 111 rotates to 150°, the energy storage operation of the common side operational mechanism is completed, and the common side clutch 110a separates from the common side drive axis 118. The common axis 111 continues to rotate, and transfers the torque to the spare side drive axis 119 via the spare side transmission gear 109b and the spare side drive gear 108b. The spare side drive axis 119 drives the spare side cam 102 to rotate, while the spare side cam 102 drives the spare side storage lever 104b to rotate and compress the spare side storage spring 103b to store energy. When the common axis 111 rotates to 300°, the energy storage operation of the spare side operational mechanism is completed, and the spare side clutch 110b separates from the spare side drive axis 119.
  • The common side cam 101and the spare side cam 102 are designed as having different curves so as to implement the aforesaid process. The common side cam 101 has a variable radius within the rotation range of 0°-150°, and has a constant radius within the rotation range of 150°-300°. The spare side cam 102 has a constant radius within the rotation range of 0°-150°, and has a variable radius within the rotation range of 150°-300°. Figure 6 and Figure 7 illustrate structure diagrams of a common side cam and a spare side cam, respectively. The radius of base circle of the common side cam is not identical to that of the spare side cam so that the cam may be precisely located when the storage spring is released.
  • In summation, according to the operational mechanism of the present invention, when the drive axis having a cam stored thereon rotates, the cam rotates the storage lever via the roller on the storage lever and drives the leader to compress the spring so as to store energy. The common side cam is different from the spare side cam. The common side cam has a variable radius within the rotation range of 0°-150° so store energy at the common side spring, and has a constant radius within the rotation range of 150°-300°. The spare side cam 102 has a constant radius within the rotation range of 0°-150°, and has a variable radius within the rotation range of 150°-300°. Thus, rotation of one circle may store energy for two operational mechanisms. The radius of base circle of the common side cam is not identical to that of the spare side cam so that the cam may be precisely located when the storage spring is released.
  • According to the gear set of the present invention, when the operating handle or motor mounted on the common axis rotates, the common side is switched via one gear, while other gears drives the drive axis of the common side and spare side operational mechanisms to rotate. The drive axis has a cam mounted thereon. When the cam rotates within 0°-150°, the energy of the common side operational mechanism is stored. After the energy storage of the common side operational mechanism is completed, the clutch device mounted at the common side separates the drive axis of the common side operational mechanism from the common axis. The common axis continues to rotate within 150°-300° so as to complete the energy storage operation of the spare side operational mechanism. Similarly, the clutch device mounted at the spare side separates the drive axis of the spare side operational mechanism from the common axis. Thus, rotation of one circle may store energy for two operational mechanisms. The gear set has a certain speed ratio so as to reduce operational forces.
  • The present invention may implement the storage operations of two independent energy storage operational mechanisms with one operating handle or motor. The operating handle is fixed on the support of the switch, and implements reliable operations with the assistance of ratchet gears and springs.
  • The present invention may provide a reliable operating system for a high-capacity integrative three-position automatic changeover switch. By utilizing energy storage operations, a relatively high switching force required by the high-capacity integrative three-position automatic changeover switch is satisfied.
  • The above embodiments are provided to those skilled in the art to realize or use the invention, under the condition that various modifications or changes being made by those skilled in the art without departing the spirit and principle of the invention, the above embodiments may be modified and changed variously, therefore the protection scope of the invention is not limited by the above embodiments, rather, it should conform to the maximum scope of the innovative features mentioned in the claims.
